SharePoint 2013 error – Unexpected response from server, The status code of response is '500'. The status text of response is 'System.ServiceModel.ServiceActivationException'.


One of my client using SharePoint standalone machine for 400 people for their internal applications. Everything working as expected but one day all of sudden got an error message saying that,

Unexpected response from server, The status code of response is '500'. The status text of response is 'System.ServiceModel.ServiceActivationException'.



This error cause due to high memory usage in the server. Verify task manager and check what service taking more time. In my case Search service taking much time. We can fix the issue using options below,

Option 1: Search Service Node Runner.exe

Reduce the Search Service Performance Level with

Set-SPEnterpriseSearchService -PerformanceLevel Reduced

As NoderRunner.exe is the process working on search service, we can limit the memory for NodeRunner.exe. But this is not recommended. We can change the configuration located in “C:\Program Files\Microsoft Office Servers\15.0\Search\Runtime\1.0\noderunner.exe.config

Option 2:  Restart servers

For Temporary solution like users wants to make SharePoint up and Running, Restart the server, so that you can see the error temporarily (You get some time to increase resources or restrict Services to specific value)

Hope this helps to resolve the issue.
