Memory gates checking failed because the free memory (373817344 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.

         I had this problem when i am trying to run the WCF services project in local . It mostly happens when the  Memory gates checking failed due to the free memory  is less than  of total memory

        As a outcome, the service will not be available for taking the  incoming requests. To fix this issue, either reduce the load on the machine or set the zero value for minFreeMemoryPercentageToActivateService in the web.config as specified below
