Hi Kevin, Sorry to hear you are having this issue. Can you please provide a screenshot of the connection properties in the configuration dialog? How quickly do those flowfiles get enqueued? I think there’s a chance if they are very small & the previous processor is very fast (i.e. RouteOnAttribute, SplitText) that it could enqueue a higher number before the back pressure check is executed.
