"Unable to connect to JGroups channel" To view the discussion, visit: https://community.jboss.org/message/765575#765575 -------------------------------------------------------------- Hi all! I manage a cluster with two servers and four nodes. Each server has two instances of JBoss EAP 5. Everything were goin on, but suddenly two nodes on the same server lost connection to JGroups and now they do not connect more. I've already checked the MultiCast UDP with McastSenderTest and McastReceiverTest programs and MultiCast UDP works. If I change the UDP address and port and start the problematic instances, JGroups works but with the UDP addres of the other server instances the problem back. Thanks in advance! Sorry for the english mistakes. This is the stack trace of the exception.
