[jira] [Created] (NIFI-1155) Processor stops running if its destination applies backpressure and expiration occurs

Mark Payne created NIFI-1155:
--------------------------------

             Summary: Processor stops running if its destination applies backpressure and expiration occurs
                 Key: NIFI-1155
                 URL: https://issues.apache.org/jira/browse/NIFI-1155
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 0.4.0
            Reporter: Mark Payne
            Assignee: Mark Payne
            Priority: Blocker
             Fix For: 0.4.0


If we setup a flow where Processor A is connected to Processor B and set backpressure to say 200 FlowFiles, all works well. If we then apply an ageoff (say 15 seconds) and start the Processors, all works well. 

Then stop Processor B so that the queue applies backpressure.
Leave Processor B stopped long enough for the expiration to occur.

The queue is now emptied, but Processor A does not continue to run.

It appears that when FlowFiles are expired while the queue is full, the queue still thinks it is full.
