Do You Get Less Than 5% Memory Error?

Issue:

Vault is no longer working and in the vlogs, you see a message with the text:

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

Cause: 

The issue occurs because you have less than 5% available memory free and by default, the program checks for 5%

Solution:

In Windows Explorer, navigate to C:\Program Files\Autodesk\ADMS <version> 2014\Server\Web\Services.
Open the file named web.config in notepad.
Find the line
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
Change it to be
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" minFreeMemoryPercentageToActivateService="0" />
Open a command line window and type the command IISRESET to reset IIS
