[Opensim-users] Help interpreting OpenSim crash console output

[Eric Riebling]

Hey, I've got an instance of OpenSim running on Ubuntu 9.04
with MONO 2.0.1 (the default), ODE physics, and 
MONO_THREADS_PER_CPU set to 50.  I experienced a crash right
after someone sent an IM in-world, with this console report.
(The last 2 lines keep repeating ["New Thread..."])

I'm just seeking help interpreting the output, if it's possible
to determine what might have gone wrong.  (Or an easy fix like
using a different MONO or threads per cpu setting)
