PrintJobMgr Uses 99% CPU
I couldn’t understand why everything on my new iMac started creeping really slow. The last straw was when iTunes started skipping.
I opened up the Activity Monitor in the Utilities folder, set it to view “All Processes”, and noticed that a process named “PrintJobMgr” was using a lot of processor time and took up over 600MB.
As it turns out, this has been discussed on Apple’s forums. It seems to be happening to people when there is a print job that never was printed, and thus is continually waiting in the print queue. I’m not sure how, but this is exactly what happened on my iMac, and deleting the print job in the queue fixed the problem.
I’m hoping Apple fixes that one soon.
