@raghavgautam Thanks for the quick reaction!
Unfortunately the newly introduced test passes without #2643, so it does
not test the original issue. Since in this modification both the server and
the client is closed gracefully the port won't stuck in TIME_WAIT state, no
need to use SO_REUSEADDR to restart new instances. To test #2643 the server
port should stuck in TIME_WAIT state and then a new server instance should be
started successfully.
I still think that it is out of scope to test an operating system level TCP
setting in a Storm test.
