Hi everyone

My proxmox server is crashing daily. And I've been checking the logs. But the thing is. What do I look for? Syslog, kern and daemonlogs. I would like to fix this problem. Need advice ! Thanks

I'm -to be honest- quite the noob. What is obvious?

Anything looking like this: http://i.stack.imgur.com/RMcUY.jpg

Anything saying "error" or "fatal" in the kernel log.

It's quite likely that you will not find anything because the machine reboots before it can write to disk. In that case, I'd start with memtest86.

Protip: view the logs in vim, it highlights errors in red.
