cabal update: /usr/hs/tools/cabal-1.16.0.2 failure (return code=-9)
haskell was installed from justhub
Does anyone have any idea why it failed? I looked for the return code of -9 but there's no information.
Update
Thanks Reid (and user5402),
Checked the dmesg and that's definitely because it's out of memory
Out of memory: Kill process 32626 (cabal-1.16.0.2) score 711 or sacrifice child
Will upgrade the machine and try again, not sure how much would cabal-install need though, I'm on a 512MB RAM system
The value -9 probably means a child process died to SIGKILL, which in turn was probably sent by the OOM killer. Checking the output of dmesg can confirm this. If that's the case, one needs to turn up the RAM available. (based on this comment).
512Mb of RAM is not enough. Instead of upgrading machine you can enable swap.
On ubuntu do following steps:
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
It will add you 4G swap file, that will prevent killing from OS.

We have a vendor who sends us photos that are hosted on Azure Edge. These photos are available and I can download them, but if we do a CURL request we get a 404 roughly 4 out of 5 times. If we do a HEAD request to get the filesize, we get a 404 about 7 out of 10 times. On our production server, we get a 404 100% of the time. Any idea how we might work around this or if there's another way to check these files without the vendor having to fix their issue?
Sample file:
curl -I http://tdrvehicles2.azureedge.net/photos/202008/1419/1850/f253435f-86b1-4cc4-b95c-7756addddad4.jpg

You may need to rerun createrepo on your local server, or run
yum clean all
on your client.
I am trying to install cabal behind a firewall without success.
It seems that cabal does not support http redirect,
is there a way to fix it?

Follow #Sibi suggestion, I pasted a similar experience using cntlm-0.92.3.
Here is my config config.ini:
Proxy proxy.swmed.edu:3128
Listen 127.0.0.1:53124
I first tried to use:
./cntlm -c config.ini
then the same error happens:

NOTE: this question is not the same as authentication, as our proxy server does not need to be authenticated. This question is about http redirect problem.
(Update) June 23, 2014
Run the following command as #Sibi suggested:
./cntlm -M http://www.google.com -c config.ini -v
And the output can be found at http://pastebin.com/zAvZBDVu
Reading the logs, we see the proxy was via https not http, and the error was "unsupported scheme" since cabal prior to recent versions did not handle https. Https transports have been added to cabal in the most recent versions, so the issue should now be resolved.

I have a problem with my server redirecting http://www.mylesgray.com:8080/ -> http://www.mylesgray.com/.
Here are my Nginx default and fastcgi_params config files:
https://gist.github.com/1745271
https://gist.github.com/1745313
This is rather a nusance as I am trying to run a benchmark of Nginx w/ caching vs Varnish w/ caching on top of Nginx to see if there is any performance benefit of one over the other.
As such I have straight Nginx w/ caching listening on port 8080 and varnish on port 80 which forwards any non-cached requests to Nginx on localhost:8080, so obviously what I want to do is run an ab benchmark on http://www.mylesgray.com:8080/ and on http://www.mylesgray.com/ to see the difference.
Here are the results of curl -I on various addresses.
# curl -I http://www.mylesgray.com:8080

So as you can see 80 is served by Varnish and 8080 by Nginx but I cannot find anywhere anything that does a 301 redirect, not in nginx.conf or in the sites-enabled/default file and I don't believe it is caused by Wordpress itself but an very much open to correction.
Please help, this is driving me nuts!

You should add a '/' at then end of your URLs. Furthermore if you run ab http://foo.com it will return you a "ab: invalid URL" error. If you do "ab -t 10 http://example.com/" everything will work fine. You should always use '/' in your URLs otherwize your webserver will try to redirect the page to the home page automatically for you which generates an undesirable extra load on the server and some extra bytes on the wire.
You web server told you what it did:
'/' is missing and something is incorrect with the port numer:
# curl -I http://www.mylesgray.com:8080
HTTP/1.1 301 Moved Permanently
[...]
======> Location: http://www.mylesgray.com/
'www' and '/' are missing:
# curl -I http://mylesgray.com
HTTP/1.1 301 Moved Permanently
[...]
=======> Location: http://www.mylesgray.com/
[...]
'/' and 'www' are missing:
# curl -I http://mylesgray.com:8080
HTTP/1.1 301 Moved Permanently
[...]
========> Location: http://www.mylesgray.com/
'hope that helps :)
The presence of an X-Powered-By: PHP header means that wordpress is issuing the 301. It's due to wordpress forcing www.mylesgray.com. When you use a nonstandard port, user agents will generally include the port in the Host: header. Try adding
fastcgi_param HTTP_HOST $host;
with the rest of your fastcgi_param directives (or alog with your "include fastcgi_params;") and it should fix this.

Did some further digging for you and found the root cause is due to misconfigured routers. You can read about it all here.
The workaround that article mentions is to:
echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale
However, this file has changed and on newer setups you need to instead:
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
You will need to be root when running that though.
