I do not think it is that. The same crash occurs on a identically
set up system on a freshly imported OAR sim. But thanks for the tip
:)<br>

in V 07.0.2 the problem wasn't there. I tried to replace

information on these ODE crashes.<br>
<br>
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.<br>
<br>
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.<br>
<br>
Compiling ODE with the older collider (GIMPACT
instead of OPCODE) doesn't see this crash.<br>
<br>
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.<br>
<br>
[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).<br>
<br>
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.<br>

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

However I noticed that the<br>
ode-file in the physics folder of DIVA is
different from the one in the original OpenSim
0.72-download. I copied that<br>
over, started the world and that seems to have
done the trick. Now I just have to figure out a

that suddenly disappeared :/<br>
