Hi,

We have deployed a website with 2 instances in Azure using the steps mentioned in Developer Guide-Deploying to Azure Web Apps. I am seeing a bunch of Timeout Exceptions and Security Access Exception in Azure app insights.Is there any configuration to avoid these exceptions?

Timeout Exception:

Security Access Exception:

Attempt by security transparent method 'System.Diagnostics.DiagnosticSourceEventSource+FilterAndTransform.IsActivitySourceEntry(System.String, Int32, Int32)' to access security critical method 'System.MemoryExtensions.AsSpan(System.String, Int32, Int32)' failed.

Assembly 'System.Diagnostics.DiagnosticSource, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.
