[Opensim-users] Standalone configuration questions

[Peter Blair]

Hi OpenSim Users and Justin Clark-Casey,

My name is Peter Blair and I’m running a standalone grid on a high end
machine with Core i7 2600 K with 16 gig of RAM with OpenSim 0.7.2 rc 2
on Ubuntu 11.04. At 20 users the sim crashes. We have four regions
running on a single standalone server. The server hardware doesn’t
seem to be fully utilized. When it crashes the server process seems to
be using 150% CPU (out of 800% possible) and 4% memory.

The users were all using university lab computers with T1 connections
and the Imprudence client viewer 1.3.2 stable version.

Is there a configuration change we can make to allow our standalone to
handle more users or is 20 generally the max for standalone? Can grid
mode handle more users reliably?

We’ve included the snippet from the crash log.


Thanks very much for your help.

Peter Blair
