REcompute virtual disk digest storm in vcenter

I am getting a constant blast of tasks in vcenter for Recomputer virtual disk digest.

I looked into this kb

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2095188

but I did not find the error in my view composer logs.

Also connecting to my ADAM database and running the query did not find any thing

any idea what this is?
