Qlik NPrinting Scheduler impossible plan error
Possible cause
The Qlik NPrinting Scheduler log file nprinting_scheduler contains an Impossible plan message like the following:
2016-01-04 13:04:50,033 [8] WARN Qlik.NPrinting.Scheduler.Service.LoadBalancer - Impossible plan connecting connections
cbd2 4073 WLoad #Req Startup Shutdown
39b7 0 0 3000 3 5000 500
327b 0 1 - - - -
4 4
This log message appears when optimization of the allocation of QlikView instances to different connection is impossible due to computation constraints.
Proposed action
The message should disappear if you reduce the number of requests in the Qlik NPrinting Engine work queue.
If the message persists:
- Check that the number of requests displayed in the #Req column is decreasing.
- Check that theQlik NPrinting Engine is working correctly and is not displaying any failures.
If the number of requests is not decreasing or the Qlik NPrinting Engine is still displaying failures, restart the Qlik NPrinting Engine service.
