CMC uses Check_MK in the --keepalive mode. That mode mixed up it's filedescriptors after a configuration reload. That resultet in the output of the checks not arriving at the CMC. The CMC waited and considered the helper as busy. All Check_MK based checks got stale. A restart fixed that.

That problem is now solved.
