"The send port configuration corresponding to the message was not found"
A message going to a one-way send port is being suspended. Reason:The send port
configuration corresponding to the message was not found.
happens when a send port was deleted while it still had some active messages.
This has sent us chasing in the wrong direction for a short while trying to think who has deleted what on the server.
Shortly after the real cause of this issue became clear through another event in the event log which noted that access to the SSO database was denied.
Of course, as the port configuration is stored in the SSODB, if access to this databsae is restricted port configuration cannot be accessed and so the message could not be delivered
