[Opensim-users] Flotsam asset cache error - process cannot access file because it is being used by another process

[Justin Clark-Casey]

I think the EOC marker problems are usually associated with corrupt jpeg 2000 textures, though I think there may also be 
a bug on 64-bit that causes issues here.

I'm not sure why you're seeing ODE errors.  I would predict that these would not go away when reverting to 0.7.2 but it 
would be something to at least try.

The file sharing issues when loading an OAR may be due to a weakness in the flotsam cache code which allows race 
conditions when cache writing is launched on its own delegate.  This should not be fatal since at least one thread will 
have correctly cached the asset.  However, it would be nice to have the failure details in a Mantis.

I think you've previously said that you have to have physical prims.  However, if you want to narrow down the problem 
you could try flipping the physical_prim = false switch in [Startup] in OpenSim.ini and see if that does alleviate the 
problem.
