 Okay, we have a varnish server in front of an image server. We recently
 tried the file storage option instead of malloc, to increase our hit
 rates.

 But it's giving us some problems. The master process will restart the
 child process on seemingly random(they are probably not random :p)
 intervals. Sometimes after 20minutes, longest it has lasted has been about
 48 hours. This last time it restarted, I saw a panic message for the first
 time. The previous reboots only produced died signal=6
