SharePoint 2013: System.ServiceModel.ServiceActivationException 500

Running out of memory is a well known bug for SharePoint 2013 search service specially because of┬ánoderunner.exe processes. Last week we had an issue with term set navigation change because of the following error: “system.servicemodel.serviceactivationexception 500”. Simply you cannot change anything. We have temporarily killed all┬ánoderunner.exe prcoesses, but it still failed.

 

Temp solution:
Enter the Windows Services list and just restart “SharePoint Host Search Controller”. After that make you should make your changes.

 

The same bug causes problems with editing SharePoint site in SharePoint Designer, simply you cannot open it. It is resolved in the same way.
