Service monitor per message exception handling
Service monitor per message exception handling

Currently the top level exception handling in service monitor
exists for process_poll_result. The issue with this scheme is
that many IFMAP messages are clumped together and hence any
exception on an intermediate message stops the processing of
the rest of the messages in the queue.  Exception should be
caught on a per message basis.
