Problems with callservicesd and soagent

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?

Thanks.
