i am newbie in network administrator..
One week ago, my server work perfectly. My Server can serves 600++ users at the same time and only use 40% cpu.
Today there is something wrong with my server. My server shows 100% cpu usage when it serves 100 users at the same time.
After i check, i found a process /boot/.IpTables that use high cpu.
What happen with my server? Is my server hacked or what?
This is SS my server process :
OK, looks like your system has been had. I did some googling for /boot/.Iptables, and it appears to be malware.

My personal recommendation would be to take the machine of the network immediately, clone the drive to a USB disk, and re-install (preferably w/ a new set of passwords, and all available patches applied).

I was running a RabbitMQ server on my Linux machine, when my disk became full I couldn't make any more connection requests to my rabbitMQ server, when I cleaned up the disk, the issue got resolved.
Yes, that is possible.
At lot of daemon do access logging. If the disk is full it might happen that logging fails and no more network requests are possible.
Side note:
If a daemon filled the disk with a log file, it might not be enough to delete the log file. You might need to restart/reload the daemon as the file isn't actually deleted while it is opened.

My client has an MS Access split database and will lose access to their in-house servers for 2 weeks to a month.
I'm thinking about building an Azure windows server and putting the back-end there, then having clients (about 12 of them) use RDP to sessions on that server (making sure that they each have the latest copy of the front-end in their own sessions).
I realize this is an "opinion" question - perhaps someone can point me to an appropriate forum - if not here.
You can do that. Any (virtual) machine running an Access database and allowing RDP access can be reached via Remote Desktop.
You may need a Terminal Server license for multiple simultaneous users.

I interrupted an install of Windows 2008 server on a fast machine that was taking too long with the intentional of using an alternative boot media to the USB flash drive I was using. (It kept showing me a message saying it was preparing my computer for first time use for nearly 2 hrs).
I therefore removed the USB drive and surprisingly it then came up with the message asking to either start in safe mode or a normal start.
I choose a normal start and it booted fine. Should I have confidence in using this as a production server or should I just go for a clean install ?
As a "production server"? You shouldn't even be asking, don't take any risks at all and redo it, it doesn't take that long.

Hello there I am currently with a host known as Site5 and they have a limit on how many "resource points" I can use. On this site, resource points are a measurement on how much hardware resources I have used.
The way they describe it in the links here state that 1 minute of CPU time = 1 resource point, and I have a daily limit of 250 points.
Since I've never used other web hosts, do other web hosts limit these sort of things?
Yes, most (if not all) web hosts do put limitations on hardware usage in some form or other. While I have never heard of it being done that way, after reading their documentation it appears to be an decent option.
I know other hosts, such as GoDaddy typically impose a hard limit but have "dedicated" resources to the site. For example, here's their grid for Linux hosting
What I have included here is what I'm used to seeing when determining hosted resources.

I have Amazon Ec2 small instance with 1.7Gb RAM. I have 3 websites running on them.
I have the scripts which does the web crawling every day and perform some caluclation.
I have not deployed them yet. But i want to know that if those scripts run for 30 mins and processor usage is 100% what will happen to websites. will they stop working or be slow.
I am not sure
Sites are like 2000 visit per day
If the script is pure CPU, which means almost no I/O usage, you can decrease the priority by nice, and your website won't be affected
