[Mono-dev] occational nunit crash

[Sean Dague]

We're running regression tests on OpenSim with every code check in on
mono, and every once in a while (1 in 20 times?) we get a failure due to
mono/nunit crashing.  These false fails are something I'd like to
eliminate if possible, as it makes people less sensitive to proper fails.

The exception that gets thrown is as follows:

Unhandled Exception: System.Reflection.TargetInvocationException:
Exception has been thrown by the target of an invocation.

Any thoughts or help would be appreciated,

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
