One ASP .NET Application is using
- SQL Server 2012
- IIS 8.5
- .NET Framework 4.0
- Windows server 2012 r2
The application is getting below error in all the load balanced application servers.

Why this error is occurring?
After restarting the IIS in all application servers, the issue got resolved. But we need to know how this is getting triggered to ensure it doesn’t happen again.
