I have a server that has been running for well over 5 months and suddently it stop responding. I couldn't ssh into it or anything else so I decided to reboot it and the reboot fixed it.
I'm trying to figure out what happened and I'm not sure exactly where to look. I started to look in
/var/log but there are tons of files in there and I'm not sure which one I should pay attention to. I'm slowly going through each one of them but if anyone can point me in the right direction, it would be great.
