<br>
if i were to quickly guess, i'm going to to assume you're not using a dedicated coordination service and are relying on the db based on your comment. if so, i would add the version of tooz you have as there are certain versions of tooz that do not handle locking with SQL well. (don't have the exact versions of tooz that are broken handy)<br>
