Joe Witt commented on NIFI-8541:
--------------------------------
the output of the broad lsof if you pick a single thing shows a repeating
pattern.
Note the first few columns. It seems like the parent process id and the child
process id are repeating in patterns as if tons and tons and tons of instances
are being launched.
