LeeAnn,
Most likely, this is a result of the inbound thread being in one process, and the outbound thread being in a different process. Sometimes the cross-process hand-off of the messages gets hosed (as there is a memory leak), and the messages start to queue in state 7 (post-Xlate). Normally, you need to stop and restart the process that the inbound thread is in to get the messages to process.
Hope this helps.
