When attempting to log into the KTA Designer or Work Space, the following error is seen:
The service '/TotalAgility/Services/core/ServerService.svc' cannot be activated
When reviewing the Application Event Viewer log, the following error can be seen:
Exception: System.ServiceModel.ServiceActivationException: The service '/TotalAgility/Services/core/ServerService.svc' cannot be activated due to an exception during compilation. The exception message is: Memory gates checking failed because the free memory (150917120 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests
This error indicates that there is not enough free RAM available on the KTA Server (Application Server) to perform the operation. To resolve this, free up some RAM on the KTA Server. This could include the need to shut down other applications, or recycle services.
Please note that a similar error could reference '/TotalAgility/Services/Sdk/UserService.svc' instead of ServerService.svc. As long as the rest of the error (Memory gate checking failed because the free memory is less than 5% of total memory) is the same, the resolution is the same.
Note: the bytes listed in the error message provided are just an example, the value seen in a different environment could be diﬀerent.
Keywords: Memory gate, RAM, ServerService.svc, UserService.svc
