.NET Forum / .NET Framework / New Users / May 2008SharedPerformanceCounter.CreateInstance exception
We have written a SOAP Extension assembly that writes timings and method counts to Performance Counter instances every time a Web Method is invoked. This has been working stably for some years. Recently one one server or another we have noticed some exceptions coming out of this assembly: System.InvalidOperationException: Custom counters file view is out of memory. at System.Diagnostics.SharedPerformanceCounter.CreateInstance(Int32 counterNameHashCode, String counterName, Int32 instanceNameHashCode, String instanceName) at System.Diagnostics.SharedPerformanceCounter.GetCounter(String categoryName, String counterName, String instanceName) at System.Diagnostics.SharedPerformanceCounter..ctor(String categoryName, String counterName, String instanceName) at System.Diagnostics.PerformanceCounter.Initialize() at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName, String instanceName, Boolean readOnly) What is the underlying cause of this exception? Can action be taken in advance to prevent this exception occurring again? We are MSDN Universal Subscribers. (munter@computershare.com) Hi Muntz, Regarding on the performance counter "Custom counters file view is out of memory" error, I've performed some research. It seems this error is likely to occur on some system which has many .NET managed performance counter instances created or running. Because the .NET performance counter use some file mapping share which has a default size limitation and if the limit has been exceed, such error is raised. #<performanceCounters> Element http://msdn.microsoft.com/en-us/library/ms229387.aspx Limits of sizes allowed: Default = 524288 Max = 33554432 Min = 32768 You can set a new value in your machine.config file (similar to this): ====== <configuration> <system.diagnostics> <performanceCounters filemappingsize="600000" /> </system.diagnostics> </configuration> ================= Sincerely, Steven Cheng Microsoft MSDN Online Support Lead Delighting our customers is our #1 priority.

(munter@computershare.com) Hi Muntz, Thanks for your reply. As for the file the .NET performance counter uses, it is not a physical file, but a memory mapping file. Also, the actual file info is controlled by the .NET framework runtime which is out of our control. So far the settings mentioned in the reference is the suggested place to configure the file size limitation.

(munter@computershare.com) I've passed the suggested fix on to our operations staff. I'll report back when this is applied. In the meantime, I've noticed a new exception: Cannot continue the current operation, the performance counters memory mapping has been corrupted. at System.Diagnostics.SharedPerformanceCounter.ResolveOffset(Int32 offset, Int32 sizeToRead) at System.Diagnostics.SharedPerformanceCounter.CalculateAndAllocateMemory(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) Any ideas? > Hi Muntz, > [quoted text clipped - 175 lines] > >>> > > >>> >We are MSDN Universal Subscribers. (munter@computershare.com) Thanks for your followup Muntz, Regarding on the new error you mentioned below: ============ Cannot continue the current operation, the performance counters memory mapping has been corrupted. ========== I've also performed some research on this. So far what I've found is that this error is possibely raised when you first call .NET performance counters classes in .net framework 1.1(or maybe other higher version) and then use .NET 1.0 classes to call the performance counters. Therefore, I'm wondering whether there are multiple applications with different versions that all use .NET performance counters classes?

Thanks for your reply Muntz, So if there are multiple version of .net framework running on it, and some of them use performance countes API, it does be possible that the problem is caused by this. I think it will be helpful if you can try isolating the problem to some certain applications(such as turn off most other applications that will use performance counters).

Thanks for your reply Muntz, I think the PerformanceCounters class should be the preferreed means to access windows performance counters. The problem you encounter is possibly due to some environment specific settings. So currently, about the two errors you mentioned 1) the "Custom counters file view is out of memory" 2) "the performance counters memory mapping has been corrupted." does the first problem got resolved after you apply the filemappingsize configuration? Or is the second error the main problem you need to address now? For the second one, it would be hard to troubleshoot from appearance, I may try finding some futher resource to continue help you, you can send me an email to "stcheng" +"@" + "Microsoft.com" so that I can ask you for further information offline. Or if you feel it an urgent issue, you can also consider contacting CSS: Microsoft Customer Support Services (CSS) at http://msdn.microsoft.com/subscriptions/support/default.aspx.
