Timers should rarely if ever be used. Each Timer maintains its own thread so this doesn't scale. On the client side a scheduled executor pool is available to the session factory and this should be used for any scheduled tasks, e.g. for http transport. Take a look at the thread pooling chapter in the user manual. We have to be very careful where and how threads are created, always use the pools unless you have a *very* good reason not to (e.g. you need to set thread priority) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4242770#...
