I would love to know what the details of your configuration are, including
web server version (Apache, Passenger, etc), and what timeouts you have
configured at that level.

I would also be interested to know what the concurrency levels you are
seeing are like on the server, and ideally what sort of I/O you have - is
this a heavily contended or slow disk, and how fast are writes generally
completing?
