[Opensim-users] Crash on collision

[M.E. Verhagen]

Happy new year !

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.

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. I
copied that over, started the world and that seems to have done the trick.
Now I just have to figure out a way to one of the sims that suddenly
disappeared :/

wich i simlinked the lib to make sure opensim uses it.  I also downloaded
https://github.com/downloads/justincc/opensim/libode.so-x86_64.so, and the
crashes stopped.
