Random shutdown

Recommended Posts

Sometimes (about once a month) my server randomly shutdowns by itself and the Screen is gone. I have to attach my server to Screen again to make it work. I thought it was a host problem but when I contacted the support, they said everything is fine on their side and something is wrong with the software I use, which is a MTA server.

Can someone help me to find what causes this problem?

I run Debian 7.0 64 bit.

Logs look fine.

What is the MTA build number?

Is there a crash dump created in mods/deathmatch/dumps/ ?

Check the OS logs to see if it reports stopping the MTA server for some reason: /var/log/syslog

That crash dump is two weeks old. Was that when you last had this problem?
