That helps.  Is this a network of brokers?  Are clients using transactions?

In addition to the diagnostics Gary mentioned, grabbing a stack trace when
this happens may be helpful.

Are JMSXGroups in-use?

Also, are the producers using the failover transport, or using any other
technology that might hold and resend messages after a broker restart?

If you can reproduce this easily with a minimal test case, then I'll give
it a try.
