I've recently started to notice really annoying problems with VisualSVN(+server) and/or TortoiseSVN. The problem is occurring on multiple (2) machines. Both running Windows 7 x64
The VisualSVN-server is running Windows XP SP3.
What happens is that after say, 1 2 or 3 (or a bit more, but almost always at the same file) the commit just hangs on transferring data. With a speed of 0bytes/sec.
I can't find any error logs on the Server. I also just asked for a 45day trial of Enterprise Server for its logging capabilities but no errors there as well.
Accessing the repository disk itself is fast, I can search/copy/paste to that disk/SVN repo disk just fine.
The Visual SVN Server also does not use excessive amounts of memory nor CPU usage, which stays around 0-3%.
Both the Server as well as TortoiseSVN's memory footprint moves/changes which would indicate at least "something" is happening.
Committing with Eclipse (different project (PHP), different repository on the server) is going great. No slow downs, almost instant commits, with 1 file or 50files. The Eclipse plugin that I use is Subclipse.
I am currently quite stuck on this problem and it is prohibiting us from working with SVN right now.

I've noticed that it goes extremely slow at 'large' files, for instance a 1700MB .resx (binary) or 77KB .h source (text) file. 'small' files > 10KB go almost instantly.

I've just added the code to code.google.com to see if the problem is on my end or the server end. Adding to google code goes just fine, no hangs at all. 2,17MB transferred in 2mins and 37secs.
I've found and fixed the problem. It appeared to have been a faulty NIC, speedtest.net resulted in ~1mbit, shoving in a different NIC pushed this to the max of 60mbit and solving my commit problems.

2.5 months ago, I was running a website on a Linux server to do a user study on 3 variations of a tool. All 3 variations ran on the same website. While I was conducting my user study, the website (i.e., process hosting the website) crashed. In my sleep-deprived state, I unfortunately did not record when the crash happened. However, I now need to know a) when the crash happened, and b) for how long the website was down until I brought it back up. I only have a rough timeframe for when the crash happened and for long it was down, but I need to pinpoint this information as precisely as possible to do some time-on-task analyses with my user study data.
The server runs Linux 16.04.4 LTS (GNU/Linux 4.4.0-165-generic x86_64) and has been minimally set up to run our website. As such, it is unlikely that any utilities aside from those that came with the OS have been installed. Similarly, no additional setup has likely been done. For example, I tried looking at a history of commands used in hopes that HISTTIMEFORMAT was previously set so that I could see timestamps. This ended up not being the case; while I can now see timestamps for commands, setting HISTTIMEFORMAT is not retroactive, meaning I can't get accurate timestamps for the commands I ran 2.5 months ago. That all being said, if you have an idea that you think might work, I'm willing to try (as long as it doesn't break our server)!
It is also worth mentioning that I currently do not know if it's possible to see a remote desktop or something of the like; I've been just ssh'ing in and use the terminal to interact with the server.
I've been bouncing ideas off with friends and colleagues, and we all feel that there must be SOMETHING we could use to pinpoint when the server went down (e.g., network activity logs showing spikes around the time that the user study began as well as when the website was revived, a log of previous/no longer running processes, etc.). Unfortunately, none of us know about Linux logs or commands to really dig deep into this very specific issue.
In summary:
I need a timestamp for either when the website crashed or when it was revived. It would be nice to have both (or otherwise determine for how long the website was down for), but this is not completely necessary
I'm guessing only a "native" Linux command will be useful since nothing new/special has been installed on our server. Otherwise, any additional command/tool/utility will have to be retroactive.
It may or may not be possible to get a remote desktop working with the server (e.g., to use some tool that has a GUI you interact with to help get some information)
Myself and my colleagues have that sense of "there must be SOMETHING we could use" between various logs or system information, such at network activity, process start times, etc., but none of us know enough about Linux to do deep digging without some help
Any ideas for what I can try to help figure out at least when the website crashed (if not also for how long it was down)?
A friend of mine pointed me to the journalctl command, which apparently maintains timestamps of past commands separately from HISTTIMEFORMAT and keeps logs that for me went as far back as October 7. It contained enough information for me to determine both when I revived my Node js server as well as when my Node js server initially went down
I have gitlab setup with runners on dedicated VM machine (24GB 12 vCPUs and very low runner concurrency=6).
Everything worked fine until I've added more Browser tests - 11 at the moment.
These tests are in stage browser-test and start properly.
My problem is that, it sometimes succeeds and sometimes not, with totally random errors.
Sometimes it cannot resolve host, other times unable to find element on page..
If I rerun these failed tests, all goes green always.
Anyone has an idea on what is going wrong here?
BTW... I've checked, this dedicated VM is not overloaded...
I have resolved all my initial issues (not tested with full machine load so far), however, I've decided to post some of my experiences.
First of all, I was experimenting with gitlab-runner concurrency (to speed things up) and it turned out, that it really quickly filled my storage space. So for anybody experiencing storage shortcomings, I suggest installing this package
Secondly, I was using runner cache and artifacts, which in the end were cluttering my tests a bit, and I believe, that was the root cause of my problems.
My observations:
If you want to take advantage of cache in gitlab-runner, remember that by default it is accessible on host where runner starts only, and remember that cache is retrieved on top of your installation, meaning it overrides files from your project.
Artifacts are a little bit more flexible, cause they are stored/fetched from your gitlab installation. You should develop your own naming convention (using vars) for them to control, what is fetched/cached between stages and to make sure all is working, as you would expect.
Cache/Artifacts in your tests should be used with caution and understanding, cause they can introduce tons of problems, if not used properly...
Side note:
Although my VM machine was not overloaded, certain lags in storage were causing timeouts in the network and finally in Dusk, when running multiple gitlab-runners concurrently...
Update as of 2019-02:
Finally, I have tested this on a full load, and I can confirm my earlier side note, about machine overload is more than true.
After tweaking Linux parameters to handle big load (max open files, connections, sockets, timeouts, etc.) on hosts running gitlab-runners, all concurrent tests are passing green, without any strange, occasional errors.
Hope it helps anybody with configuring gitlab-runners...
I read all the rules on asking good questions here, I hope this will suffice.
I am having problems with an Access 2016 .ACCDE database.
The program runs fine on my machine. When I try to run it on my friends' machines (either the .ACCDE or .ACCDB version) it won't load and pops Out Of Stack Space errors and the Security Notice instead.
So, here's the set up:
The program was written in Access 2016. It is a Front End/Back End design. It's not a very big program 16 tables, 41 forms and 51 code modules.
I use the FMS Access Analyzer to help make sure my code is clean so the quality of the program is good to very good.
PRIOR versions of the program ran fine on all machines. I made several changes, improvements and moved it to the \Documents folder. Now we are having problems.
Machine 'A' (Development PC): New Win 10, 8GB RAM, Full MS Access (not runtime).
Machine 'B': Newish laptop 2GB RAM, lots of disk, Access 2016 Runtime. It ran prior versions of the program fine but now is blowing errors.
Machine 'C': Newish desktop 8GB RAM lots of free disk, full Access (not runtime). It also ran prior versions of the program fine but now is blowing errors.
Initally, the opening form would pop an error that the On Load event caused an Out Of Stack Space event. User says,
"Still happens after a fresh reboot. It does NOT happen with other .accde files." Both A and B machines are showing the same errors.
I made many changes but could not cure the Out Of Stack Space error. Finally, I went to an Autoexec Macro instead of a startup form. The autoexec macro that caused Error 3709 and aborted the macro. Machine B had CPU 49%, Mem 60%. The micro sd drive had 5.79GB used and 113GB free.
I deleted the macro. Went back to startup Form, still no luck.
I asked if he got a MS Security error, he said, "Yes, Microsoft Access Security Notice. Figuring just a general warning since it let's me go ahead and open the file. The directory where we have the program (C:Documents\Condor) was already a Trusted Location on my work machine."
So, does this sound like a Security error?
Is it a problem to have the program in the \Documents folder?
okay well there's a lot going on in this post - so to sanity check I would suggest getting back to basics: working just with .accdb and full license - - does it throw any errors at all?
an aside: because with runtime an error = crash....usually it just rolls over and closes without any message.
an aside: you don't need .accde for run time as it can't affect design, only if there are full license people you want to keep from going into design view would you need accde.
you have to be sure that the runtime / accde machines have the exact same path to the back end as your full license machine's path - as the path is stored in the front end
but sanity checking the accdb on the full license machine is the first step in debugging this... if this is not all okay then must be dealt with first.
I'm sorry, I thought I had posted that the problem was resolved.The table links broke because, as you pointed out, one person's This PC\Documents\whatever folder is different from anyone else's. (C:\Users\KentH\Documents\whatever vs. C:\Users\JohnT\Documents\whatever)
Thank you for your time and suggestions. Broken table links can cause the stack error, fer sure, and that can be caused by trying to put programs someplace other than the C:\Programs folder.
D'oh!
So, I have a collection of Windows Server 2016 virtual machines that are used to run some tests in pairs. To perform these tests, I copy a selection of scripts and files from the network on to the machine, before performing the tests.
I'm basically using a selection of scripts that have existed around here since before my time and whilst i would like to use other methods, so much of our infrastructure relies on these scripts that overhauling the system would be a colossal task.
First up, i sort out the mapped drives with
net use X: \\network\location1 /user:domain\user password
net use Y: \\network\location2 /user:domain\user password
and so on
Soon after, i use rsync to copy files from a location in /cygdrive/y/somewhere to /cygdrive/c/somewhere_else
During the rsync, i will get errors that "files have vanished" (I'm currently unable to post the exact error, I will edit this later to include this). When i check what's currently in the /cygdrive directory, all i see is /cygdrive/c and everything else has disappeared.
I've tried making a symbolic link to /cygdrive/y in a different location, I've tried including persistent:yes on the net use command, I've changed the power settings on the network card to not sleep. None of these work.
I'm currently looking into the settings for the virtual machines themselves at this point, but I have some doubts as we have other virtual windows machines that do not seem to have this issue.
Has anyone has heard of anything similar and/or knows of a decent method to troubleshoot this?
Right, so I've been working on this all day and finally noticed a positive change, but since my systems are in VMware's vCloud, this may not work for some people. It's was simply a matter of having the VM turned off and upgrading the Virtual Hardware Version to the latest version. I have noticed with this though, that upon a restart, one of the first messages that comes up mentions that the computer is "disabling group policies".
I did a bit of research into this and found out that Windows 8 and 10 (no mention of any Windows Server machines) both automatically update Group Policies in the background, disconnecting and reconnecting mapped drives to recreate them.
It's possible that changing the Group Policy drive from "recreate" to "update" should fix this issue, and that the Virtual Hardware update happened to resolve this in a similar manner.
Hoping some SysAdmins can weigh in here, because I am most assuredly not one.
OS: Ubuntu Server 14.04
CMS: Expression Engine 2.9 (with extras, such as Expresso Store)
Server type: Virtual
Error: Segmentation fault (11)
Unable to load the webpage because the server sent no data. Error code: ERR_EMPTY_RESPONSE
We do not believe it is a code issue on the ExpressionEngine side of things, and my research indicates it is normally something awry on the server itself or externally (browser, ISP, etc). Issue is, no matter where in the country one accesses this particular page on the site it will routinely fail, specifically in Chrome.
The client cannot launch the site in its present state so we have been scrambling to find an issue.
While playing detective certain facts became known to me.
The virtual server is owned by the client themselves and the physical boxes are located at their facility. Their lead IT professional, who has absolutely no real experience with Linux, has been maintaining the box and the OS. This last point is critical, because he has been updating any and everything on the server the second it appears on the list. They have indicated that, for them, this is normal procedure for their Windows servers.
This set off a few alarm bells.
The IT professional has been doing this for many weeks without us knowing, and the error started happening on the 5th of September. This coincided with two updates made by him, one of which was ligbcrypt11 amd64 1.5.3-2ubuntu4.1 . This has remained unchanged since September 5th.
Could this be causing the issue? Does anybody know of any problems afflicting specifically Chrome regarding the server sending no data?
An aside: I have attempted to use GDP to backtrace the problem, but I cannot get Apache to actually generate an error file out in the folder located in /tmp that I created. When I look at the logs it does say that a dump file could be located there, so the code I placed in apache2.conf is clearly working. Permissions and ownership have been set for the folder.
I made the following changes to try and get it to work:
etc/apache2.conf (file location)
CoreDumpDirectory /tmp/apache2-gdb-dump (code added)
/etc/sysctl.conf (file location)
kernel.core_uses_pid = 1 (code added)
kernel.core_pattern = /tmp (code added)
fs.suid_dumpable = 2 (code added)
There are so many things that could be happening that I just don't know where to start with this. This isn't my area of expertise.
