Subject Re: How to configure fixed range of ports for (Storm/Netty) internal TCP connections.
Date Mon, 15 Apr 2019 09:30:56 GMT
It would be good to know which commands those Java processes are running.
Could you try getting the output of "jps -lvm <pid>" for the Java processes
that have the ports open?
