[ https://issues.jboss.org/browse/JGRP-1743?page=com.atlassian.jira.plugin.... ] Dennis Reed commented on JGRP-1743: ----------------------------------- Opening in response to an outage with a major customer, where a misconfiguration (multiple JDG caches accidentally clustered together, some using NAKACK and some using NAKACK2, so no messages were ever cleared) caused an OutOfMemory situation when NAKACK/NAKACK2 had GB's of memory worth of messages. We've also seen large retention before in NAKACK due to a bug. NAKACK should never have a huge number of messages in a normal situation, so this seems like a pretty easy place to put a warning that something is wrong if the number of messages gets too high. -- This message is automatically generated by JIRA.
