FD_SOCK port conflicts with concurrently connected channels
-----------------------------------------------------------
Key: JGRP-1314
URL: https://issues.jboss.org/browse/JGRP-1314
Project: JGroups
Issue Type: Bug
Affects Versions: 2.12.1
Reporter: Paul Ferraro
Assignee: Bela Ban
Because of the high level of concurrency in AS7, I'm seeing occasional socket
exceptions in FD_SOCK when trying to start multiple channels using a shared transport. It
appears that there are some thread safety issues with the port increment logic within
FD_SOCK.
Until JGRP-790 is complete, measures need to be taken to ensure that multiple concurrently
connected channels do not select the same port on which to open a server socket.
Here's a sample stack trace:
