Enterprise Portal Installation fails due not enough memory
2. August 2013 Leave a comment
A typical Dynamics AX 2012 (R2) installation requires lot of RAM to work properly. Especially SharePoint, the basis for Role Center and Enterprise Portal want’s lot of it. I came across an issue where EP installation failed. The DynamicsSetupLog.txt revealed the issue; an exception at the SecurityTokenService.
The service ‘/SecurityTokenServiceApplication/securitytoken.svc’ cannot be activated due to an exception during compilation.The exception message is: Memory gates checking failed because the free memory (723009536 bytes) is less than 5% of total memory
There are some blogs regarding this issue: Restart NodeRunner, Set the App Domain, Configure minFreeMemoryPercentageToActivateService . The simplest solution however is to provide more memory
