I am getting the below error from the Windows Application logs. This keeps recurring almost every day. Server has to be restarted every time the issue occurs. 

Database statement execution error encountered.  Session ID: 90724; Dialog ID: 7761336; Repository: 'SEWA-Laserfiche'; CLI routine: MaterializedSearch::ResultSet::~ResultSet; Message: [Microsoft][SQL Native Client]Communication link failure; SQL Statement: 'delete from searchresult4 where rsid = ?         '; SQL variable: ''; SQL State: 08S01.

I have attached the SQL error log that shows at that particular time as well. Any thoughts?
