JVM crash.

[werner291]

Hello, I was trying to run a Minecraft server (both vanilla and bukkit) on my CentOS vps.

It keeps crashing a few minutes after startup, and I found this file next to the jar. Can someone tell me what I'm doing wrong?

It says in the log Thread blocked a few times. Maybe there are some security issues?

[werner291]

I'm relatively inexperienced with CentOS. What exactly do you mean with "security issues"?

[ozzyman]

I dont know a thing about CentOS. I was just speculating on the error messages. I dont know why a thread should be blocked but one thing what seemed to be like a logical answer was that the thread could have been blocked if it tried to do some operation it did not have the permission to do.

[werner291]

Rebuilt my server to use Debian instead of CentOS. It appears to be running like it should now. (Who knows for how long...).

EDIT: Ok, near-immediate crashes are happening again...
