[jboss-user] [JBoss Seam] - IllegalStateException: could not acquire lock on @Synchroniz

Don't know how to reproduce this one but it's happening on noteAction which is a session-scoped SFSB which is injected into a conversation-scoped SFSB. I have seen it a few times now even after I restart Jboss 4.2.2. What does this exception mean (i.e. why can't it acquire a lock?) | Exception during request processing: | Caused by javax.servlet.ServletException with message: "javax.el.ELException:
