Server stops responding, can't find issue?
- by Corey W
I've had a pretty basic server up and running CentOS with webserver/database, and have noticed that it has locked up a few times in the middle of the night. It seems to happen randomly.
When it locks up I can ssh in, (although it seems to hang once connected), but can't access cpanel/whm and have to reboot the server to get everything back up.
Checking the messages log I see the below like clockwork every 5minutes 1 second, and then it just stops logging anything until I reboot. I can't seem to find any log showing any issue? Is there somewhere I can check to try to figure out what is happening?
Could this be caused by CPU being maxed?
