My server crashes about once a week and does not leave any kind of clue as to what's causing it. I have checked
/var/log/messages and it just stops recording at some point and starts at the computer post information when I perform a hard reboot.
Is there something I can check or software I can install that can determine the cause?
I'm running CentOS 7.
Here is the only error/problem in my
