Have you tried deleting the libode.so from the bin dir and using justins libode-86_64.so ?

Essentially, we've narrowed it down to a problem using the default ODE collider with more than 1 region. Stress tests with 20 bots constantly teleporting around one region (or between two simulators in a grid each running 1 region) do not trigger the ODE crash even after many hours. The same stress test with 20 bots teleporting between two regions on the same system, even where the regions are 10 map spaces apart, always triggers the collider crash sooner or later. Sometimes this occurs almost immediately, sometimes only after an hour or so. Compiling ODE with the older collider (GIMPACT instead of OPCODE) doesn't see this crash. My chief suspicion is that there's actually an ODE/collider memory freeing bug. I suspect that it's not very usual to run more than one physics 'world' in a program (in OpenSimulator, each region runs its own world). It could also be a problem with OpenSim's P/Invoke interface to ODE causing collision objects to be freed at the wrong time, but I'm currently discounting that because we don't see the same failure with two simulators each with a single region, and ODE scenes at the OpenSim level are entirely separate, even though they aren't in the ODE library itself. [1] contains a link in the comments to an ODE Linux 64 bit library I compiled using the GIMPACT collider, if you're running that platform and want to try it. This will work on any recent version of OpenSim (probably even 0.6.9). Using a linux distro version of ode probably won't fix this problem as I expect they will have compiled it using OPCODE. OpenSimulator only every uses the ODE library bundled in its bin directory, unless you start symlinking or similar.

One other thing what seems to trigger ode crashes seem to faulty meshes, you can reconize these from opensim log lines like: 10:49:19 - [MESH]: no recognized physics mesh found in mesh asset 11:06:40 - [MESH]: asset data is zero length 06:40 - [MESH]: experimental mesh proxy generation for defaultMesh/9af57c73-8ef4-**42f1-9415-46e8491213cd Try to find these inworld and delete them. On my box the ode crashes were less fequent after deleting those. The case with the libode is that it does not seem to be compatible with some systems luckely most system already have a libode in their repo why not use that libode ? I am using a git version, not the diva. Could be that some recent updates on the odescene also prevent some crashes. Op zaterdag 31 december 2011 schreef Klaus-E.

However it did not fix the problem :/ Istill got the same crash. However I noticed that the ode-file in the physics folder of DIVA is different from the one in the original OpenSim 0.72-download.
