SharePoint 2013 Server - Unexpected response from server. The status code of response is '500'. The status text of response is 'System.ServiceModel.ServiceActivationException'
When everything is working fine and suddenly you start receiving an error while the SharePoint page loads, "Unexpected response from server. The status code of response is '500'. The status text of response is 'System.ServiceModel.ServiceActivationException'". That too from only one front end server. First thing first;
- Remove the front end server from the load balancer.
- Now your site is fine for end users, but not for you ;)
- Login to the front end server where the issue is occurring.
- The issue occurs mostly because of occupied memory. If memory utilization is more then you will receive this error.
- Right click on Task manager and check the memory occupied.
- The users who are logged into the servers and forgot to log off has occupied space.
- Right click on the username and force log off them; except your userid ;)
- Refresh the SharePoint site, the error is no more.
- Enable the server in the load balancer again.
Cheers !
