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 may be essentially operating 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.

> I had the impression that I could force it by clicking in the admin interface
