Check_MK Werk 6396: Fixed 'Unhandled exception 452' in master control snapin if EC Daemon was disabled via 'omd config'

ID: 6396 Title: Fixed 'Unhandled exception 452' in master control snapin if EC Daemon was disabled via 'omd config' Component: Site Management Level: 1 Class: Bug fix Version: 1.6.0i1 Workaround: After setting MKEVENTD option in 'omd config' run 'cmk -U' in order to update the core config. Internal notes: After disabling MKEVENTD via 'omd config' and 'omd start' the tactical overview fails while contacting the mkeventd via the socket tmp/run/mkeventd/status in order to gather information about open and acknowledged events. This happened because the core config was not updated via 'cmk -U'.
