When attempting to upgrade the subscriber to 3.2 from 3.12c I get the error, "unable to find a valid callmanager installation error please install the callmanager softare before applying this update" When I verified that all of the callmanager services are running, I noticed some performance issues (slow windows and the like) I looked at Task Manager and saw that the ccm.exe is constantly taxing the CPU at 99%!!!!
I have already upgraded the publisher to 3.2 with no issue. I have used the same 3.2 image to upgrade the subscriber that I used to upgrade the publisher.
The servers are MCS-7835's. Is there some special procedure to upgrade the subscriber? What parameters is the update using to verify there is a callmanager already loaded? This is driving me nuts. Anybody out there got a clue with the heck is going on?

You should contact TAC..or just rebuild your subscriber and check if you still have the same problem. I just got a note from TAC regarding other issue
CSCdw22999 can cause a Call Manager restart since it produces a high CPU condition on the Call Manager trying to connect to the non-existant services on the other nodes in the cluster. That's why the workaround would still be adviseable for them."

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
