body: <p>This is my SQL Server 2008 R2:

  <p>Every now and then, my sql server is crashing.
  When a query is sent to server after it has crashed, this is the error message I get:</p>
  
  <pre><code>[08001] : .  [HYT00] : Login timeout expired [08001] : Unable to complete login process due to delay in prelogin response
  </code></pre>
  
  <p>Any idea what this error is about? Also, how can I figure out what is causing the server to crash?</p>
  
  <p>There is not many logs in the windows log viewer:

  <p>Looking at the memory usage / cpu usage, it appears normal also. CPU is at 1% and memory usage is at 97%.</p>
