Test-ExchangeSearch fails with “Time out for test thread”

We recently found that Test-ExchangeSearch cmdlet was failing on our Exchange 2010 SP2 installation with error Time out for test thread. 

Exception: The exception thrown is : System.InvalidOperationException: Custom counters file view is out of memory.

at System.Diagnostics.SharedPerformanceCounter.CalculateMemory(Int32 oldOffset, Int32 totalSize, Int32& alignmentAdjustment)

at System.Diagnostics.SharedPerformanceCounter.CreateInstance(CategoryEntry* categoryPointer, Int32 instanceNameHashCode, String instanceName, PerformanceCounterInstanceLifetime lifetime)

at System.Diagnostics.SharedPerformanceCounter.GetCounter(String counterName, String instanceName, Boolean enableReuse, PerformanceCounterInstanceLifetime lifetime)

at System.Diagnostics.SharedPerformanceCounter..ctor(String catName, String counterName, String instanceName, PerformanceCounterInstanceLifetime lifetime)

at System.Diagnostics.PerformanceCounter.Initialize()

at System.Diagnostics.PerformanceCounter.IncrementBy(Int64 value)

at Microsoft.Exchange.Diagnostics.ExPerformanceCounter.IncrementBy(Int64 incrementValue)

Last worker process info : Last worker process info not available!

The problem is that by default in Exchange 2010 not more that 52 databases (any state Mounted/Unmounted) so that get listed available under MSExchange Search Indices Counter. To work around this issue you can add the following Dword value

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchange Search Indices\Performance

DWORD VALUE FileMappingSize

 Decimal Value 1048576

We also created Msftefd.exe based on the  Kb2837276 to resolve the issue.
