softwareupdated process high CPU usage
I have a user with a fully updated Mavericks running on a mid-2010 Macbook Pro. She's been complaining of slowness on her system, and checking the Activity Monitor, I'm seeing the softwareupdated process taking up 90 to 115% of the CPU, for about 10 seconds at a time, about every 3 minutes. It shows up, spikes to the top of the Activity Monitor, then disappears again.
She's fully updated, so there's no reason it should be checking so often, and as a precaution I even turned off Software Updates, trying to figure out what the problem could be. That hasn't fixed the problem.
Any ideas on what else I can check or how I can resolve this?
