I really hope someone can help me here!
I am running c-panel and WHM. The server has been fine until Thursday when it started behaving strangely.
One of the sites on the server was having issues with the max_allowed_packet variable being set too low so I edited /etc/my.cnf to increase the sql variable max_allowed_packet from 1mb to 16mb.
However, since around making this change one of the sites on the server keeps drawing heavily on the cpu's usage - exceeding 100% - which causes the server to reboot (it is stuck in a loop of rebooting).
Does anyone have any suggestions on how to get the server back to normal? I can't get in to edit the file before the server resets at the moment. I've tried killing the site that is causing the cpu overload, but when I try to kill it says it doesn't exist.
