             Summary: DistributedEventReceiver utilizes long-running session
                 Key: SLING-8002
                 URL: https://issues.apache.org/jira/browse/SLING-8002
             Project: Sling
          Issue Type: Improvement
          Components: Event
    Affects Versions: Distributed Event Admin 1.1.2
            Reporter: Jörg Hoh


We recently came across this warning in our logs. Looks like the DistributedEventReceiver uses a long-running session, thus causing warnings from Oak.

Either the scope of the session should be reduced, or the session should be refreshed before writing.
