Error while configuring Build controller / Http code 500 System.ServiceModel.ServiceActivationException"


Issue: While configuring Build controller you might see Http code 500 System.ServiceModel.ServiceActivationException” error in TFS Admin Console.


Cause: This is due to the fact that Team Foundation Server Application Tier machine had has less than 5% memory(RAM) available.

This is by design with regards to WCF type calls, they may fail if server has less than 5% of memory available.

Resolution: Free up memory on TFS Application Tier. in our case we set a limit to how much SQL server can use memory and that freed up memory. After which we were able to configure Build fine.
