Anybody ever experience "hanging" send/receive sessions? A comms session will run and finish successfully but it is not released by the process controller. It remains active yet there is no log for it in the mailbox properties. All subsequent comms sessions will then queue up behind it and do nothing. The net effect of this is to completely stop all external communications and the only fix is to reboot the machine. This thing is driving me nuts. It happens at random, it seriously impacts on production and Sterling have not a clue what is going on.
