title: SQL Server running slow due to thread count increase
body: <p>On our production server, for some reason at specific amount of time, thread count goes over and over to the certain point that though CPU Utilization is normal(30-50%), but the query starting to run slow we so lot more blocking statements.</p>
  
  <p>I am not sure where to look at it, basically when our site runs normally, the thread count is around 150 threads, but during the specific time in a day(during 1:30 to 2:30) it come up to 270 threads.there are no extra sql transaction goes on, everything as normal as it was before but thread count grows and sql start behaving very very slow.</p>
  
  <p>After restarting the SQL service immediately thread count comes to normal, and our site function fine for another 24 hours.</p>
  
  <p>We are using SQL Server 2005, it is 24 core machine.</p>
  
  <p>any idea?</p>
