We have just opened an issue (https://jira.jboss.org/browse/HORNETQ-535) for (what seems to be) a deadlock that occurred overnight with TRUNK.
We have not been able to reproduce the issue yet, but have taken a heap dump and a copy of the data and log directories. Unfortunately, this comes to nearly 310MiB (compressed) which is a bit large to post. Do you want the files split into pieces or should we find another way to make the files available to you?
