[jboss-user] [Clustering/JBoss] - Re: Potential issue with JGroups using JBoss 3.2.7 and Java

If this sort of thing happens, take several thread dumps and look for threads that aren't progressing.  As with the MessageDispatcherThread here though, a thread that's "not progressing" because it's sitting in wait() is usually not an issue.  Look for threads that aren't progressing while they wait to acquire a lock; then find the thread the holds the lock. No guarantee that you'll find your problem, but it's an approach that often helps.

Here I *suspect* there was something going on with one of the transactions referred to in the log messages at the end. No idea what though.
