[Opensim-users] OpenSim 0.7.4 teleport failures

[Justin Clark-Casey]

If you're using mono 2.10, I would suggest trying

[Startup]
async_call_method = UnsafeQueueUserWorkItem

This uses the built-in thread pool for launching various threads rather than a SmartThreadPool instance (which is the 
current default).  Evidence so far is associating the STP with these kinds of issues, though this is not conclusive at 
this point.

It appears that UnsafeQueueUserWorkItem works fine on Mono 3 and I believe it's fine on Mono 2.10 (though more evidence 
is welcome).  However, reports say that it is problematic on Mono 2.4, probably due to deficiencies in the built-in Mono 
threadpool implementation.
