Unable to Start “Output Post Processor” Concurrent Manager

After starting concurrent manager I noticed "Output Post Processor" did not start. I tried to start "Output Post Processor" using "Administrator Concurrent Manager" screen but it failed with given error in manager log file

 

Error

Unable to initialize state monitor.

Resolution

I notice "Service Manager" was down. So I restarted "Service Manager" and then restarted "Output Post Processor". Concurrent manager started successfully.
