Just a FYI, this is probably related to the heightfield. Backup
your terrain and then reset it to a flat one and try again.

BTW in V 07.0.2 the problem wasn't there. I tried to replace
the old libode from 0.7.2 with the ones from the old version,
but Opensim would no longer start. So I assume something has
changed with the physics from one version to another.

Please see [1] and [2] for more information on these
ODE crashes.
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.

Basically I am using the DIVA because of the wifi,

one myself atm.

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.

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 :/

installed ode on my system with 'yum install

from the opensim bin dir, after wich i

it. I also downloaded
https://github.com/downloads/justincc/opensim/libode.so-x86_64.so,
