Your account was suspended due to inactivity. Remember that its a requirement to log in to the forums once every. I unsuspended you.

Certain components/extensions use excessive RAM or CPU.
If you list any extensions that you use, someone can suggest which one may be causing the suspensions.
The suspension is automated. The high resource usage is high usage of RAM or CPU.
What plugins/modules do you have installed for joomla? I find cache scripts tend to trip the scanner.
hmm. Are you sshing into it or using the console connection in the control panel.
If you can connect to it via ssh, the first thing i can think of is either bad resolve.conf or some rouge iptables setting.
You can use ftp or cpanel's file manager to change or remove files.
PHP files are scripts that use CPU. A script heavy in Loops or that uses allot of very large variables would probably get auto-suspended.
If a script you made is causing the suspension, you can ask here for help here...
