Joe Witt resolved NIFI-8541.
----------------------------
Assignee: Joe Witt
Resolution: Information Provided
This suggests that the system using NiFi where the file count continues to grow
is using Java 8 update 271 I believe it is. Update the JDK version and ensure
NiFi is using that and you should be fine again. If that does not solve it
then we need the complete output of running lsof so we can get a better sense
of what is in there. That said, the very likely problem is the buggy JDK
version. It had to do with certain types of sockets leaking. It occurred in a
very specific JDK and went away right after that.
