System.Diagnostics.PerformanceCounter.InitializeImpl() error

[EcTomBot]

Describe the bug

After upgrading the library from version 6.0.2 to version 6.1.1, creating a connection to SQL Server

string connectionString = @"Data Source=SERVER\SQL2016;Initial Catalog=GeOM;Integrated Security=True;User ID=;Password=;MultipleActiveResultSets=True;Application Name=EntityFramework;Encrypt=False";
SqlConnection _connection = new SqlConnection(connectionString);

generates the following error:

Exception message:
System.InvalidOperationException
Applicazione: GeOM.exe
Versione framework: v4.0.30319
Descrizione: il processo è stato terminato a causa di un'eccezione non gestita.

Hi @EcTomBot,

I'm unable to reproduce this issue against .NET 9.0 or .NET Framework 4.8.1, using a variety of locales.

Could you provide the following information:

• .NET SDK - What SDK are you using to build.
• Target Framework - What frameworks are you targeting, for example .NET 9.0, .NET Framework 4.8.1, etc?
• .NET Runtime - What runtime is running the app.
• Locale - What locale/culture are you running in, for example Italian (it_IT)?

It would also be helpful for you to provide a minimal project that reproduces the issue.

Hello, I just had the same problem on one of my servers. This server don't have performance counters ".NET CLR Data", no problem on the other servers that have this counter's category. Check on your server in perfmon.msc.
Regards

[EcTomBot]

Thanks, Christ
As you suggested, loading the following .Net Performance Counters solved the problem:

lodctr "C:\Windows\INF.NET CLR Data_DataPerfCounters.ini"
lodctr "C:\Windows\INF.NET CLR Networking_Networkingperfcounters_v2.ini"
lodctr "C:\Windows\INF.NET CLR Networking 4.0.0.0_Networkingperfcounters.ini"
lodctr "C:\Windows\INF.NET Data Provider for Oracle_DataOracleClientPerfCounters_shared12_neutral.ini"
lodctr "C:\Windows\INF.NET Data Provider for SqlServer_dataperfcounters_shared12_neutral.ini"
lodctr "C:\Windows\INF.NET Memory Cache 4.0\netmemorycache.ini"
lodctr "C:\Windows\INF.NETFramework\corperfmonsymbols.ini"

You may not need to upload them all, but just to be safe... :-)

[theprev]

I hope that it will be fixed, adding the performance counter is not the right solution ....

[RichardD2]

Just run into the same issue on a 2016 server. The workaround from EcTomBot worked, after I restored the path separators that seems to have been stripped out by the Markdown processing:

lodctr "C:\Windows\INF\.NET CLR Data\_DataPerfCounters.ini"
lodctr "C:\Windows\INF\.NET CLR Networking\_Networkingperfcounters_v2.ini"
lodctr "C:\Windows\INF\.NET CLR Networking 4.0.0.0\_Networkingperfcounters.ini"
lodctr "C:\Windows\INF\.NET Data Provider for Oracle\_DataOracleClientPerfCounters_shared12_neutral.ini"
lodctr "C:\Windows\INF\.NET Data Provider for SqlServer\_dataperfcounters_shared12_neutral.ini"
lodctr "C:\Windows\INF\.NET Memory Cache 4.0\netmemorycache.ini"
lodctr "C:\Windows\INF\.NETFramework\corperfmonsymbols.ini"

We also encountered this issue with Microsoft.Data.SqlClient 6.1.1. One of our servers was missing performance counters, which resulted in the error:

The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly.

This was for a .NET Framework 4.8 MVC 5 app. We apply Entity Framework 6 migrations using EF6.exe, and that's when we'd receive the error.

We were able to resolve the block by installing the counters. Specifically the .NET Data Provider for SqlServer was the one needed to unblocked.

However, we later had an outage with the error:

Custom counters file view is out of memory.

We run several tenants (IIS sites) of a multi-tenant app across many shared pools, and are required to run them at 32bit to save on resources. We attempted to bump filemappingsize to the max allowed of 33,554,432 bytes (https://learn.microsoft.com/en-us/dotnet/framework/configure-apps/file-schema/trace-debug/performancecounters-element), however the error would return.

In the end we rolled back to Microsoft.Data.SqlClient 6.0.2.

[dziedrius]

Having the same problem here, was chasing the problem for two days and pulling my hair (completely bold now).

It was on our lab server, so we thought we have too many app instances going and that causing the issue, but even after reducing .net processes count, we were facing same issue:

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.InitializeImpl()

at Microsoft.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key)
at Microsoft.Data.SqlClient.SqlConnection.set_ConnectionString(String value)

The worst thing - it is random, we were reproducing it often, but not every time (again, we run ~200 .net processes on that server, so that might contribute a lot to the problem).

Tried to add registry keys to increase file mapping size, settings to machine.config, nothing helped, this was very very confusing.

I've tried to look into the code, but there's too much stuff going on to understand it quickly, even for troubleshooting purposes.
Also using Windows SQL 2016 server.
