Hi, I have hit a corner case that I have a simple fix for (I'm hitting it with clustering + the row-locking=true feature) . I described it in the user forum (seemed like the right place to post it). http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046639#... I've worked in other AS areas more than the ejb2 container but have learned a lot of the internals over the last few months. If there is agreement that I should fix this, I'll jira/fix it. Thanks for your feedback (Scott/Bill?), Scott
