Hi Dano Seems that the problem has been seen by a few people but until now nobody from NiFi team really cared about it – except Mark Payne. He mentioned the part below with the diagnostics, however in my case this doesn’t even work (tried it on standalone unsecured cluster as well as on secured cluster)! Can you get the diagnostics on your cluster?
I guess at the end we have to open a Jira ticket to narrow it down. Cheers Josef One thing that I would recommend, to get more information, is to go to the REST endpoint (in your browser is fine) /nifi-api/processors/<processor id>/diagnostics Where <processor id> is the UUID of either the source or the destination of the Connection in question. This gives us a lot of information about the internals of Connection. The easiest way to get that Processor ID is to just click on the processor on the canvas and look at the Operate palette on the left-hand side. You can copy & paste from there. If you then send the diagnostics information to us, we can analyze that to help understand what's happening.

The only resolution is to disconnect the node and then restart that node. After this, the flowfile disappears from the queue. Any ideas on what might be going on here or what additional information I might be able to provide to debug this? I've attached another thread dump and some screen shots.... Regards, Dano
