Rest API stop working due to “minFreeMemoryPercentageToActivateService”

Question

I am working on an on-premise SharepPint 2013. and the site collections are working well. but on a specific screen i wrote a javaScript will call the Restful API for a list. and this script was not working correctly. so i tried to access the REST API using my browser and i got this error:-

Memory gates checking failed because the free memory (141824000 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.

so can anyone adivce on this please? again the site collections are working fine,, and i am able to view/edit/delete items. but the problem is happening on the REST API.

So can anyone adivce on this?

Thanks

Answer 1

This issue occurs if the available memory on the web server is low So

• Try to restart Sharepoint search host controller in windows service to release all the leaked memory and consumed memory !
• Or scale up your memory.

• Also, check the following links to adjust minFreeMemoryPercentageToActiveService Configuration Setting as a permanent solution.

  • Mitigation: minFreeMemoryPercentageToActiveService Configuration Setting
  • SharePoint Memory gates checking failed because the free memory is less than 5% of total memory.

As Qassas mentioned you have to check the resources on the server.

• check which process is consuming the memory alot
• stop all the services / app pool which are not being used. to free up memory
• if you are not using the Search stop that service as it is biggest consumer of memory all the time.
• dont create too many web application, keep single web application with mutliple site collection.
• How much memory you have ( if it is really less than increase it).
• lastly you can reduce the number 5 if it is your dev machine.
• if you have Anti virus on the server please stop it.
