             Summary: ConnectException error messages when using TCP protocol
                 Key: JGRP-2357
                 URL: https://issues.jboss.org/browse/JGRP-2357
             Project: JGroups
          Issue Type: Bug
            Reporter: Dante Wang
            Assignee: Bela Ban


When using TCP protocol with JGroups 4.1.1 Final, various kinds of java.net.ConnectException error messages occasionally appear in the log. These exception log messages were by default suppressed with logging level "TRACE" before JGRP-2332 (commit 538a5431b8fd06d644a72f48d584f8114f26a295).

The ConnectExceptions in this case happen upon attempts to discover nodes, verify node status when another node dies and send ACK when another node leaves.

The ConnectException messages of node discovery can be avoided by carefully changing configuration of TCPPING or using other ping like JDBC_PING. But the two kinds of messages upon node exiting seem to have no way to avoid.
