Random shutdown

[Drakath]

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.

[ccw]

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

[Drakath]

There is a crash dump: http://www67.zippyshare.com/v/87594783/file.html

[ccw]

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

[Drakath]

I had it today.

syslog looks fine:

[Drakath]

Ah, I had it again today. Any idea who could cause this?

[Woovie]

Provide a newer crash log.

[Drakath]

There is no newer crash log.

[Woovie]

Sounds like maybe it's hitting resource limits?

[Drakath]

It looks fine to me:

I am a concerned about the traffic though.

Here are the specs:

Bandwidth: 100 Mbps (10000 GB per month)

CPU: 3 vCores
