In ConversationEntry : I tried to replace return lock.tryLock( Manager.instance().getConcurrentRequestTimeout(), TimeUnit.MILLISECONDS ); with | lock.lock(); | return true; | Which replacing the failing lock with a waiting lock. With the example from above with the loop, the flooding seems to work also it makes the page a little dizzy (because all calls to getTotal get executed serially). But in normal operation it works perfectly. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080207#...
