Proxy 'DWProd Word Automation Services': Exception connecting to service application: System.ServiceModel.ServiceActivationException: The requested service, 'http://myserver:32843/fc23852d4cbc4511b3be479864b55de3/Service.svc' could not be activated. See the server's diagnostic trace logs for more information. 

When you browse  this URL 'http://myserver:32843/fc23852d4cbc4511b3be479864b55de3/Service.svc: Server is having less than 5% of memory , try after some time. Forgot to take snap shot.

Solution

Release the server from hitting 100% memory and rerun the code by limiting the number of PDF conversion to lesser number in our case it is set to 25.
