Hi 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.
Maybe you're just running out of memory with the increased packet size? What are you server specs and what system logs are saying?
