Bryan Bende commented on NIFI-916:
----------------------------------
While testing this patch, NiFi shutdown correctly every time, but I did
sometimes encounter this warning while shutting down. I suspect as it is a
warning not an error that it is ok, but wanted to make note of this:

> When I issue the bin/nifi.sh stop command, running in CentOS 7 in my VM, I
> occasionally get a timeout exception. If this happens, it will continue to
> happen until I manually kill the process.
> Below is the output that I receive, as well as the results of running netstat
> to verify that NiFi is in fact listening on the port reported.
