[jboss-jira] [JBoss JIRA] Created: (JGRP-985) Admin Join problem -GMS flush by coordinator failed

Admin Join problem -GMS flush by coordinator failed ---------------------------------------------------- Key: JGRP-985 URL: https://jira.jboss.org/jira/browse/JGRP-985 Project: JGroups Issue Type: Bug Affects Versions: 2.7, 2.6.5, 2.6.4, 2.6.3 Environment: linux redhat 2.9.6, jdk 1.5 Reporter: Ronn C Assignee: Bela Ban Attachments: jgroup.tar.gz I am experiencing a problem with jgroups trying to join existing cluster. Occasionally, new node joining a existing cluster can experience this problem. 2009-05-21 12:04:02,568 [main] WARN org.jgroups.protocols.pbcast.GMS:144 - join(callisto.tmca.com.au-18715) sent to callisto.tmca.com.au-8185 timed out (after 3000 ms), retrying Retries can varies from a couple of times to infinitely retrying. Debugging the code, I've discovered that before join the coordinator will perform a GMS flush and unless that GMS flush success it won't reply with a join response. So sure enough at the coordinator, I see this log. 2009-05-21 12:05:25,902 [ViewHandler,callisto.tmca.com.au-8185] WARN org.jgroups.protocols.pbcast.GMS:749 - GMS flush by coordinator at callisto.tmca.com.au-8185 failed I've originally come across this problem in our prod environment with 2.6.3. I have been able to replicate it reliably with 2.6.3. I have tested with 2.7.0 and 2.8.0.alpha3 and retries still occurs but generally it would sort itself out within a minute. However, I've found that retries can still occurs infinitely on 2.8.0 if you keep repeating the test often enough. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
