If a timeout occurs in a Windows agent section while executing WMI queries the related services were handled as vanished services by the Check_MK Discovery service. This may be misleading because this timeout is short-lived.

The WMI query timeouts are a known problem in Windows and can not be solved by the Check_MK agent. Please see https://github.com/martinlindhe/wmi_exporter/issues/89 for further information.

Now the Check_MK Discovery does not take WMI timeouts into account. Thus the Check_MK Discovery does not report "vanished services" any more. The Check_MK service handles services with WMI timeouts as "stale" further on.
