After upgrade from UIM 8.51 to 9.02 the service_host probe is in fail state.
The functionality of service_host probe has been implemented into wasp probe since UIM 8.5. So after an upgrade from UIM 8.4x to 8.5x this probe should have been removed already.
UIM 8.51 upgrade to UIM 9.02
Deactivate the service_host probe and delete it in IM or USM
