[jboss-jira] [JBoss JIRA] Commented: (JGRP-1155) Socket Exceptions on Coordinator after adding start_port in FD_SOCK

Socket Exceptions on Coordinator after adding start_port in FD_SOCK ------------------------------------------------------------------- Key: JGRP-1155 URL: https://jira.jboss.org/jira/browse/JGRP-1155 Project: JGroups Issue Type: Bug Affects Versions: 2.6.10, 2.6.13 Environment: RHEL 5.2. 135.9.147.170 is coordinator, 135.9.147.158 is other member Connection is over TCP Jgroup Channel is over port 7802 FD_SOCK is over port 7803 iptables is running, which is why I need to specify a port; the random port selection gets blocked otherwise Reporter: Ken Michie Assignee: Bela Ban Fix For: 2.10 I was able to reproduce it with Draw program on both 2.6.10.GA and 2.6.13.GA. Here is my command: java -cp .:log4j.properties:log4j.jar:jgroups-all.jar:commons-logging.jar org.jgroups.demos.Draw -props kenTcp.xml log4j.properties was on WARN and above for org.jgroups. I would tail the jgroups.log file and ONLY on the coordinator I would eventually see these messages printing every so often: 2010-02-16 15:49:43,144 [ConnectionTable.Connection.Sender local_addr=135.9.147.170:7802 [135.9.147.170:50167 -
