NPrinting task run successfully but occasionally the same task failed. It is happening with different reports not only same one.
Below is the error message from the NP scheduler log:

• Failed generation of report xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx for user xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx  
• ERROR: System.Exception: Exceeded maximum number of retries

Environment

Resolution

Steps to resolve the issue:

Part 1

1. Stop all NPrinting services
2. Navigate to C:\Program Files\NPrintingServer\NPrinting\Scheduler
3. Make a copy of scheduler.config
4. Edit scheduler.config
5. Add <add key="max-requeue-attempts" value="20"/> to the file, at the end of the list but before the closing tag (</appSettings>)
6. Restart NP services

You may also increase the value as needed (for example 30, 40, 50).

Note: If this does not resolve the task from failing, please restore the original file and go to Part 2 below.
