Problems with JBOSS cluster --------------------------- Key: JGRP-2068 URL: https://issues.jboss.org/browse/JGRP-2068 Project: JGroups Issue Type: Bug Affects Versions: 2.6.10 Reporter: Fouad Zoghlami Assignee: Bela Ban Attachments: the master.zip, the slave.zip We are using a JBOSS cluster for the Process Server component. One node (the master) is used for Process Workplace and a second node is used by an external application to start new process instances from the scanner input. Recently they encountered a problem where one of the 2 nodes started to give problems. When we look in the logs it looks like there is some kind of communication problem between the 2 nodes in the cluster. From that point it looks like the cluster is repaired, but from that point the process server on one of the two nodes begins to give problems when users try to send on workitems. It looks like the locking state is out of sync or something like that. In all situation we have been able to fix the issue by restarting jboss on both nodes and clearing the /tmp, /data and /work folders Please see the logs file. Issue happened around 2015-11-12 10:48:35. It happened also 2 weeks ago and a couple of months ago. Please assist in finding the cause of this behavior and how we can prevent this in future.
