I run a very small FTB server with very few people on it (about 6 at max). The server that's running on is fine and I am not running out of ram or dropping below 20TPS.

However, about once every 2 hours or so the server just stops responding, with no output, no error and no crash report. The java thread is still running and the port it's self is still open/listening but the server will not respond. There is not activity in the log. If I type commands into the server console (ssh) I get no response. If I hit ctrl+c the server responds with "Stopping Server" but it never stops.

I have checked /var/logs for any indication that the kernel is causing the issue (i.e. killing it for more ram or something) and can't find anything.

Like I said there is no error in the console, the log, or in crash logs. The server just stops, but the process stays open. In help in troubleshooting this problem would be appreciated.

I have tried this with Ubuntu 12.04

I have used java versions

Sun Java 7
Sun Java 6
OpenJDK 6
OpenJDK 7

all of them exhibit the same pattern. However, I can not make it "crash" on any specific timeline or action. Sometimes it crashes when no one is on, sometimes when only 1 or 2 people are on. Others when the server has 8 people (all of us at the moment).

If there is anything I can do to help troubleshoot please let me know.
