BBW stops sending messages after a few minutes

Jul 6, 2011 at 8:18 PM

Intermittently I have observed that BBW or rather LoadGen would stop sending messages in the middle of a test run.  Perf counters show steady processing rate until all of sudden Documents Received flattens out.  Processing rate of course then drops to 0.  Database sessions for the receive host drops suddenly as well.  No indication of problem on BizTalk side.  No throttling and messagebox tables are clean after documents stop coming in.  Thread count and memory usage for the receive host remain steady.  BBW continues to run after this, giving no indication of failure as well.  At the end of the run, we get failure result as expected.  I suspect this may be a LoadGen issue rather than BBW.  But wondering if anyone has been it before.

I bet you got several events in the eventlog complaining about sessions being in failed state. That usually indicates BizTalk is not able to process the load. Also have a look at the throttling counters to see if BizTalk is throttling.
