TFS Build Controller service HTTP code 500: System.ServiceModel.ServiceActivationException

Question

I have configured the TFS 2013 build service but the build controller fails after 5 seconds with error

Please contact your administrator. There was an error contacting the server. Technical information (for administrator): HTTP code 500: System.ServiceModel.ServiceActivationException

I tried modifying the web.config Program Files\Microsoft Team Foundation Server 12.0\Application Tier\Message Queue but no luck

Answer 1

Take a look at Task Manager on the machine where your TFS Repository lives. We have this problem whenever its memory utilization is greater than 95%.

Answer 2

Had the same issue and in our case it was resolved after lowering the memory usage of the server.
