Sage X3 v12p32

Per title.

No idea on cause but I have a print job here which cannot be killed from Reports > Print Supervision (PSIMP) and it is taking up 1/5 max concurrent print queue.

I have tried to turn off the print server but the print job is still back, with the print job entry coming from the runtime server.

Other than restarting the whole infrastructure, is there any way to remove it?
