After cache generation of a connection between Nprinting and qlikview, qv.exe process is not closed / killed

[Sonja_Bauernfeind]

Scenario:

• After cache generation of a connection between Nprinting and qlikview, qv.exe process is not closed / killed
• This causes high RAM usage in the Nprinting server.. This could sometimes cause the server to crash or Nprinting server failing completely.
• NP engine is forcefully closed leaving open background tasks and qv.exe and renderer.exe running in the background

Environment: 

Qlik NPrinting , 17.x.x and newer

Cause:

Forcing the NP engine service closed via task manager leaves unfinished tasks and background processes in memory.

Resolution:

• Allow the NP scheduler service to close QV.exe and renderer.exe processes gracefully. 
• If the NP services do not close gracefully, restart the NPrinting server to clear all processes running in the background.
