Memory Leak

[hakkuo23]

Ok, Minecraft crashed on my machine, so I ssh into it this morning, and I find this error:
INFO] Starting Minecraft server on 64.74.97.92:25565
Stacktrace:


Native stacktrace:

mono() [0x4911ea]
mono() [0x4e064f]
mono() [0x41b187]

mono() [0x51e838]
[0x40368496]

Debug info from gdb:


=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================

Also memory usage is at 75% and the server isn't even running. How can I find out what's hogging my ram?

Here is top:

WTF?!?!? Java isn't even running lol

The fact that the error you quoted talks about mono tells me that it was generated by something other than Java, as Java does not use mono. If you're running a server wrapper that requires it, it could be that the wrapper crashed, and Minecraft is still running in the background and no longer being managed.

Definitely try to kill that hog with "kill 10060". If that doesn't work, "kill -9 10060".

Ok, that seemed to fix it, but it's still crashing. This is the only error I get

FOUND A FIX (server hasn't crashed in 1hour)
sudo nano /etc/cron.d/php5

# 09,39 * * * * root [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -depth -minde$

It's a bug with php5 in ubuntu oneric.

Nevermind lol. Still having the issue.

PHP should not be involved.

With Java only using 1.3 GB of of its virtual 12.2 GB, you aren't seeing a problem due to memory usage. Your error with java.util.ConcurrentModificationException is likely from a bug in a plugin.

What is your full log information? What is your command line? Did you install the server as we recommend at http://www.nfoservers.com/forums/viewto ... =67&t=5049? Have you stopped using the wrapper and begun running it directly?
