Troubleshooting
Problem
Intermittently, all users simultaneously receive an error
The problem is intermittent
- It is relatively rare (by default it will never occur more than once a day, but normally it is much rarer than that)
- It is not triggered by any particular user action. For example, it can occur when the user is completely idle (for example a user goes to lunch, comes back, and sees the error).
Symptom
Different symptoms appear inside different environments (for the same root cause). Therefore, the exact error that the end user sees may vary.
Example #1

The connection with the server was lost
You will be logged off from Controller Link!
Example #2:
2019-07-08 17:27:12,897ERROR System.String - A SOAP Exception was received when calling UserManager_KeepAliveSystem.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Security Error 1 at Cognos.Controller.Proxy.SoapExtension.ServerExtension.ValidateNativeUser(SoapMessage& message) at Cognos.Controller.Proxy.SoapExtension.ServerExtension.ProcessMessage(SoapMessage message) at System.Web.Services.Protocols.SoapMessage.RunExtensions(SoapExtension[] extensions, Boolean throwOnException) at System.Web.Services.Protocols.SoapServerProtocol.CreateServerInstance() at System.Web.Services.Protocols.WebServiceHandler.Invoke() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest() --- End of inner exception stack trace ---
