title: [proxy_fcgi:error](70007)The timeout specified has expired
body: <p>I am facing a weared issue with my Magento webstite... its goes down after every 1-2 days. Error is Error 503 Backend Fetch Failed. Guru Meditation. 
  When I check apache logs it shows "[proxy_fcgi:error] [pid 3910:tid 140273111668480] (70007)The timeout specified has expired: [client 127.0.0.1:55123] AH01075: Error dispatching request to :81: (polling)"</p>
  
  <p>I doubts that it is issue with apache as it cannt return responce to varnish... I have checked few blogs and as per them Timeout need to be increased in apache.But i dont see any configuration like this.</p>
  
  <p>After restating the server website works fine for 1-2 days.</p>
