[Opensim-users] Crash on collision

[Klaus-E. Klingner]

Hallo,

since updating to the new DIVA build (16915) my server keeps crashing 
when an avatar bumps into something with this message:

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.
=================================================================

This also happens when I am opening an object and then close the 
Edit-window.

I am running the simulator on OpenSuSE 11.4 - 64bit with

Mono JIT compiler version 2.10.2 (tarball Mon Apr 18 15:12:52 UTC 2011)

The sim is started in a screen:

#!/bin/sh
cd /opt/opensim/diva-r16915/bin
TIME="OpenSim Down, Restarting: `date +"%A, %B %d - %r"`"
echo $TIME >>/opt/opensim/logs/os.log
cd /opt/opensim/diva-r16915/bin
ulimit -s 262144
screen -fa -S OS -d -U -m mono OpenSim.exe -console

Any tips?

Regards,
