We've been seeing issues , three times now, where it seems like a flowfile is stuck in a load balanced queue. We're not able to empty the queue or view the flowfile that appears to be in the queue. The only resolution for use right now is to detach the node where the Flowfile is in the queue, then restart that node. After that, the flowfile is gone.
I've enabled the expire flow files after X time, but that doesn't appear to help...
