concurrent manager has timed out waiting for the Output Post-processor to finish this request

The Following error had occured while running the xml report “concurrent manager has timed out waiting for the Output Post-processor to finish this request”

Cause:

Once the Output Post Processor picks up the request, the XML Publisher engine is invoked to generate the final output file. The time that this takes will depends on various elements such as:

• size of the XML Data File
• complexity of the template
• performance of the server
• ….

By default a timeout will occur if it takes longer then 300 seconds (5 min.) for the XML Publisher engine to generate the output file. The Concurrent Request will complete with status Warning and the Request log file will contain Error Message

Solution:

Increase the value (in seconds) for the profile option ‘Concurrent:OPP Process Timeout’.
