Joe Witt commented on NIFI-8541:
--------------------------------
Ok.....lets maybe slow down a bit and focus on the specific problem statement
of what you need to solve rather than the symptoms you might be seeing.
"ListFTP processor on centos 7 cluster. It work well before can not list file."
That appears to be the root issue that led you to look at other aspects. I see
no sign of a real leak yet. The lsof -p output is pretty authoritative and
looks normal as far as I can tell. The flow/logs you show reflect nothing
abnormal at all but that makes sense since it is an empty flow/default started
node.
Lets go back to ListSFTP.....before centos7 it worked great. Now it doesn't.
What does NiFi see when listing now? Nothing? What errors happen? If it is
not working there should be errors or there should be nothing which means it is
connecting and looking and getting no results. So...please share what you're
seeing for that issue itself.
