Question

Java consuming >25% CPU after ML upgrade

I just upgraded my Mac Pro to Mountain Lion. I notice that the fan is going more frequently, and the computer just sounds like it's working hard most of the time. It's not spotlight, because I killed indexing (I don't use it). I opened Activity Monitor and I see that java is consuming between 20 - 35% of CPU resources with no applications other than finder open. This doesn't seem right. Any ideas?

Mac Pro 2.8 (Early '08), Mac OS X (10.5.2), 10 GB RAM, 74GB 10k Raptor, 2x 750GB RAID, 23" ACD

Actually, I edited the message because I realized that java is conuming that much CPU even with no other applications open other than Finder.

That was confusing....

Okay, I don't even see Java in my Activity monitor and I have lots of stuff open.

Do you have any login items in the Users & Groups tab of System Preferences? Also, anything in the following folders?

macintosh hd > library > launch agents

macintosh hd > library > launch daemons

I just figured it out. It's CrashPlan, an offsite back-up service I use. I read reports elsewhere that it hogs java in Mountain Lion, and I ran a Terminal command to confirm that it was happening on my system. It is. Now I need to contact them. Thanks.

I have crashplan installed too. But even after exiting the application the cpu usage persists. I even checked to see that it is not running in the menubar.
