Service error - "Memory gates checking failed because the free memory (xxxxx bytes) is less than 5% of total memory."

I was testing few service scripts when I encounter with this error -

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

Resolution:

Adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element or your project config file.

The easiest way just add this into your web.config

<system.serviceModel>
<serviceHostingEnvironment minFreeMemoryPercentageToActivateService="0" />

</system.serviceModel>
