Issues with the softwareupdated daemon after upgrading to Yosemite? Ever since the upgrade to Yosemite, the softwareupdated process always consumes around 100% CPU. 

I noticed this the other day when I closed my laptop at the end of the day and the area above the left side of the keyboard was very warm. Looking at Activity Monitor, the softwareupdated process was running at full blast. That also explains the horrible battery life that I have had since upgrading. 

I waited to upgrade to Yosemite until after the first xx.xx.1 point release and ever since then the softwareupdated runs constantly, no matter how many times that I kill it. 

Is there a solution for this?

MacBook Pro, OS X Yosemite (10.10.1)
Disconnect from the network and reboot the Mac.

Then see if the process can clean itself up. Assuming it is under control, open system preferences and turn off all automatic checks under the app store pane.

At that point you can reconnect to the internet and see if things are solid before opening the App Store app again.
