I am currently running the last Yosemite public beta version. On both my desktop and laptop I frequently see on activity manager that the processes callservicesd and soagent are racing along using 100% of CPU each. Messages which I think is related to these processes often shows the same behavior. I kill the processes but within half an hour they are back and racing along.

Is anyone else having this problem? Is this something which might be fixed by upgrading from the public beta to the release Yosemite? I had the same issue with soagent and callerservicesd eating up all CPU. The problem is related to a contact syncing issue with iCloud. Resolution: Open the console and filter for messages from 'MCContactsManager'.

In the details of the message, you can find a reference to the contact causing the issue. Export this contact to a VCF file. Delete the contact and check that there are no more messages from 'MCContactsManager'.

Watch out for soagent and callerservicesd to relax (should use much less CPU now). Now you can import the saved VCF into contacts again and everything should be back to normal. OK so I took it upon myself to do some research because I was not getting the response I required quick enough. I personally have protools on my computer. So I followed the instructions on going to the library and updating the plug ins. Go to your computer go to library go to audio go to plug-ins go to HAL see what kind of Plug-In you have, mine was DigiDesign remove plug-in and reinstall This stopped my issue with the coreaudiod, callservicesd, & identityservicesd.

I have not seen these stop responding in the past 3 days. However I am still having some issues with slow response going between functions on my computer. Which I do not understand because I have 45GB open on my hard drive. But it is no where near as bad as it was before. Over the next week or so I will be removing a lot of pictures, video and music onto external hard drives. Cleaning my desktop, and getting rid of programs I don't use.

I hope this helps because it was really frustrating for me. I had the same issue with soagent and callerservicesd eating up all CPU. The problem is related to a contact syncing issue with iCloud.

I have searched for MCContactsManager and ' AddressBookSync: The shared address book could not be loaded. In the console and didn't find them. I also unlinked Contacts from iCloud. I also followed the directions above to remove com.apple.soagent.plist and restarted the computer. Every time I try to open Messages, it won't actually even open anymore - it just says 'not responding' and takes up 99% of the CPU. Soagent doesn't seem to be taking up much CPU anymore.

What else can I try? The Genius bar doesn't have appointments available for 3 more days! Any more ideas? I use Messages all the time, so hate to be without it! I posted a response below on the thread, but wanted to make sure you saw it, since you seem really knowledgeable! Also, I was wondering if I should somehow update the Messages app, but I don't know how to do that.
