Check_MK Werk 0314: Fix CMC not executing any Check_MK checks after config reload

ID: 0314 Title: Fix CMC not executing any Check_MK checks after config reload Component: Core & Setup Level: 2 Class: Bug Fix Version: 1.2.5i1 CMC uses Check_MK in the <tt>--keepalive</tt> 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.
