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 Priority: Major Fix For: 4.1.2 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.
