The issue is with automatic acknowledgements in OFTP when receiving files for sites that have  the "Ack by monitor" option set on. The normal flow of event should be:

   - a file is received
   - the route state is then switched to "processing"
   - after emitting the EERP, the transfer enters the routing phase

Now, what happens if the Monitor is abnormally stopped just after the transfer was switched to the "processing" route state but an EERP was not generated?
The EERP won''t be generated after the Monitor is started again and the transfer will be stuck.

It is possible to resume the transfer processing by changing the route state as follow:

   1 - peladm update_trans -i <transfer_id> -rs TO_ROUTE
   2 - peladm update_trans -i <transfer_id> -rs PROCESSING

This way the EERP will be created and the transfer will enter the routing phase.
