Failed and Blocking Correlation is a very bad situation, as this error
blocks all other jobs behind it in the Queue. Failed and Not Blocking
Correlation does not block other jobs behind it in the Queue. Hope this
helps.
You have asked me such a general question that I could not possibly answer
it. If you want an answer from anyone in this newsgroup, you will need to
give us a LOT more information about the Queue failure. Hope this helps.
