Kev- Thanks for you work over the past few days :) If you want to join the messaging team there are vacancies ;) Regarding the executor - good catch. Actually this queued executor was a last minute addition to workaround another remoting issue. BTW are you creating/destroying a lot of sessions rapidly now? If so, pls bear in mind that sessions are also fairly heavyweight objects so this would be considered an anti-pattern too. This is why the JCA layer for instance, caches underlying JMS sessions.
