"Output Post Processor" Concurrent Manager not able to start R12.1

I tried to restart but still getting the same status. Later on I tried to query the "FNDOPP"
 process on the application tier
$ ps -ef|grep -i FNDOPP|grep -v grep

Manager Log Said: 

Unable to initialize state monitor.

Solution:

I restarted "Service Manager" and then restarted "Output Post Processor".

 Concurrent manager started successfully.

As the image Above.

Thanks.
