In env with 2 CAS and 3 MB Servers, all 2013 CU3, the ProcessIsolation healthset is market as Unhealthy. Here is the result from the monitor:
"
< Message > Maintenance workitem "Process.Isolation.Maintenance.Workitem" (ID: 64) has failed. Health Manager has detected it is either set to run once and failed, or has been failing consistently. Maintenance workitem failure could cause monitoring gap and should be investigated. The error message from the last result is: workitem completed with result: TimedOut ------------------------------------------------------------------------------- States of all monitors within the health set: Note: Data may be stale....<Result from Get-HealthReport here>.........
Note: Subsequent detected alerts are suppressed until the health set is healthy again. </ Message >
"
Using get-serverhealth I can see that "ProcessIsolation\MaintenanceFailureMonitor.ProcessIsolation\" is Unhealthy.
I cannot find any documentation regarding this Healthset. How should I investigate this?
