[Opensim-users] ODE physics exception

[John Hopkin]

Loading a region, I'm getting many thousands of errors from the ODE
plugin for sculpted prims that are not physical. The text of one such
error is pasted at the end.

The region is connected to OSGrid, and was functional before the
recent 0.7.1 upgrade. All but one other regions connected in the same
way have no major problems. The region in question contains something
like 8600 prims, mostly sculpted.

OpenSim is 8731c2b, OS is Ubuntu Meerkat latest; database is MySQL
14.14;  Mono is 2.6.7; physics is Meshmerizer/ODE.

Any ideas? Thanks

John
