Memory gates checking failed because the free memory (xxxxxx bytes) is less than 5% of total memory

When we are trying to execute the WCF Rest service but the service will run properly in the local system but after installing it on to the server it gives the above error

 The solution is simple just set the parameter minFreeMemoryPercentageToActivateService to 0 in the web.config file  

<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" minFreeMemoryPercentageToActivateService="0" />
