FIX: Repeatedly Retrieving Remote Performance Counters May Fail with Status 1450 (327795)


The information in this article applies to:

  • Microsoft .NET Framework
This article was previously published under Q327795

SYMPTOMS

When you repeatedly retrieve performance counters on a remote computer, the PerformanceCounter class may fail with status 1450, and you may receive the following error message:
Insufficient system resources exist to complete the requested service.

CAUSE

This error occurs because performance counters are implemented by using the RegistryKey class. When your program gains access to remote performance counters, the PerformanceCounter class calls Microsoft.Win32.RegistryKey.OpenRemoteBaseKey.

Remote registry keys are opened as System keys. There is a bug in the .NET Framework that does not close these System keys when you are finished with them. Because there is a limit of 65,535 open System keys, when your program gains access to remote performance counters more than 65,535 times, you receive the error message in the "Symptoms" section.

RESOLUTION

A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next .NET Framework service pack that contains this fix.
