Subject Re: Pending messages on queue is stale or wrong

What version of ActiveMQ are you using? 
There have been a number of bug fixes around duplicate detection in the past few releases.

Perhaps you got some duplicate messages in your store that the cursor would not dispatch because
it detected them as duplicates. 
This should generally not happen, the duplicate should not get written to the store in the
first place. 

If you're not at the latest and greatest version of ActiveMQ, I would suggest to upgrade.

Otherwise it would be interesting to find out how to reproduce the problem so that it can
be analyzed further.
