I have encounter the following error:
----------------------------------------------------------------------------
--------------
Service cannot be started. System.InvalidOperationException: Cannot create

----------------------------------------------------------------------------

There error has occurred after numerous time of running the application
without such error. The performance counters were created and also read
from PerfMon. Perhaps am I encountering some file or registry corruption?
Code:
----------------------------------------------------------------------------

Dim pcc As PerformanceCounterCategory
If Not pcc.Exists("XHPR") Then
Try
Dim perfCounters As New CounterCreationDataCollection()
perfCounters.Add(New CounterCreationData("Msg Errors", "",
PerformanceCounterType.NumberOfItems32))
perfCounters.Add(New CounterCreationData("Oversize Msg
Errors", "", PerformanceCounterType.NumberOfItems32))
perfCounters.Add(New CounterCreationData("Processed Msgs",
"", PerformanceCounterType.NumberOfItems32))
perfCounters.Add(New CounterCreationData("Proc In Use", "",
PerformanceCounterType.NumberOfItems32))
perfCounters.Add(New CounterCreationData("Backend Auth
Errors", "", PerformanceCounterType.NumberOfItems32))
perfCounters.Add(New CounterCreationData("Queue Depth", "",
PerformanceCounterType.NumberOfItems32))
pcc = pcc.Create("XHPR", "XHP Regulator", perfCounters)
Catch e As Exception
Write2Log(e.ToString, EventLogEntryType.Error)
End Try
End If
pcMsgs = New PerformanceCounter("XHPR", "Processed Msgs",
Me.ServiceName, False) ' **** Line 316 ****
pcMaxMsg = New PerformanceCounter("XHPR", "Oversize Msg Errors",
Me.ServiceName, False)
