title: Issue with Redis or server configuration
body: <p>We have 3 dedicated servers from Hetzner and experience the same issue that is described here: <a href="http://code.google.com/p/redis/issues/detail?id=500" rel="nofollow">http://code.google.com/p/redis/issues/detail?id=500</a></p>
  
  <p>We have built an advertisement network that delivers about 200k ad impressions per day, and in some days when we have more traffic than usual, then we start getting errors and lose impressions. </p>
  
  <p>Web server and Redis are running on separate servers. We have tried using 2 different redis connectors (phpredis extension and predis library), but still experience the same issue - "connection timed out" errors from time to time.</p>
  
  <p>We've tried increasing various limits in redis.conf without any luck.</p>
  
  <p>Both servers have CPU power and memory to spare.</p>
  
  <p>Maybe anyone has some new ideas, how to solve this?</p>
