Document was stacked


We are using IS and broker 6.5 .
and facing the problem that stacking the document in the queue .
Have you face such a problem.
If you know the problem on JVM or IS and broker issues, Please let me know .


Long back we faced this problem on 6.0.1 Dev system. The triggers just don’t pull the documents from broker wihout any reason. We couldn’t solve that problem by any means except restarting IS.
Any thoughts on this???


Thank you for repry .

Is it a possibility bug of WM because it has been happened by even 6.0.1?

Are you able to replicate this by some means?
