Description

Originally reported on the mailing list as a MiNiFi issue, https://lists.apache.org/thread.html/d64afc392d8c503997634ed4e9285ba4e89ccc83002e99c66d259c89@%3Cusers.nifi.apache.org%3E.

After some initial evaluation it appears there is a bug being triggered in the mqtt library that is not being handled by NiFi and causing a resource leak.

Original thread here:
https://lists.apache.org/thread.html/d64afc392d8c503997634ed4e9285ba4e89ccc83002e99c66d259c89@%3Cusers.nifi.apache.org%3E

Additional details to follow as I evaluate how to trigger it.
