> We have a ListSFTP processor which produces 1'500'000 flowfiles as output.
> When we try to "Empty Queue" it takes multiple minutes and the GUI shows a
> HTTP 503 error during that period. We can't open the GUI again until the
> deletion is complete. Those flowfiles are all on the primary node and not
> load balanced within the cluster. Below is the final GUI message. The
> intermediate message looks similar but without the removed string.
