When performing MultiGet, unloading AppDomain crashes the host #103

This is due to EventWaitHandles already being destroyed, and mre.Set() being called in a finally block -- it leads to unhandled ObjectDisposedException that kills the host application (IIS pool in our case). Encasing mre.Set() with try/catch(ObjectDisposedException) block in async callbacks (MultiGet, Stats, maybe in other places) should alleviate this problem.

I have the same issue.

We have the same issue. As the following code fragment in 'PerformMultiGet' executes on a ThreadPool thread, there is no way for an application to recover from this.


An edited crash report :

System.ObjectDisposedException was unhandled
Message="Safe handle has been closed"

We are going to fix this on the Couchbase fork of this project: http://www.couchbase.com/issues/browse/NCBC-198
