[Opensim-dev] Any Ideas??

[Justin Clark-Casey]

I personally would doubt this is connected with physics.  That said, it's difficult to say what the issue would be.

Below, you could try setting ScriptStopStrategy = co-op.  This stops scripts by having them regularly check whether they 
should stop rather than aborting their thread, which has caused Mono crashes and other Mono VM instability in the past 
if there are scripts very actively llDie()ing or being removed.  This setting is now default in development code.

In 0.8 it is not default.  The setting is present and works but there is no mechanism for automatically doing the 
necessary script recompilation.  However, as you're running DeleteScritpsOnStartup = true this won't be an issue. 
Documentation at [1].

If this doesn't help then:

* Does this happen on every region or just some?
* Is this reproducible every time?
* What do you mean that "xengine status" show scripts waiting?  You mean something other than

Work items waiting         : 0

?  Could you paste the "xengine status" output you see when you have these issues?
