There is an issue with crashed dock and high cpu usage (nearly 100%) caused by Bootcamp applications directory on the dock. If you take it away from dock the dock will not crash anymore. Or you can disable it in the config window of the VM. I called Apple support because iu had no idea what's going on. The 2nd level support knew about this problems with the dock and Parallels Bootcamo Applications directory.
I had the same problem this morning. I had no idea it was Parallels until I stumbled across this via a Google search. Thanks.
No, I did not know about the KB article, but that is exactly what I did in my VM and it worked for me. Thanks.
