Hi All,

We have set up search service on sharepoint 2013. I have created a separate content source for my site collection and crawled. It is taking more than the time needed and not ending with the crawl status. It is showing "No data" message in the crawl log with 0 success, 0 failure, 0 errors and 0 top level errors. When i try to search from my site collection: The error am getting is:

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

Event Logs Error:

Our environment set up is as follows:

1. Single server with sql 2012 and sharepoint 2013 ( Dev environment)

2. RAM: 10 GB

3. Hard disk space: 119 GB

Please help with your inputs.

You don't have enough free physical memory. You can close some program on the server to free up some memory. With single server installation, you should set the maximum memory used by SQL server.

And please install SharePoint 2013 March PU, i noticed that the memory consumption by search service is less after this PU. By the way, the latest update is April CU.

Hi Yuming,

Thanks for the help. We were able to fix it by limiting the sql memory to 4 GB. It started loading the results.
