    [ https://issues.apache.org/jira/browse/CONNECTORS-1180?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14497892#comment-14497892

Karl Wright commented on CONNECTORS-1180:
-----------------------------------------

FWIW, if you are using Zookeeper with multiple agents processes, it is possible that the underlying
cause of this problem for you is a misconfigured cluster.  If, for example, you have multiple
instances of Zookeeper and they are not talking to one another, then each cluster member essentially
operates independently.  For performance reasons, ManifoldCF's stuffer thread uses Zookeeper-based
locking to prevent an active document from winding up in more than one queue.  If that locking
is not working, then a document can be processed by more than one worker thread at the same
time, leading to precisely this kind of result.

saw 4"
> I had the impression that I could force it by clicking in the admin interface
> and for instance when I pressed refresh in "Status and Job Management".
