Lighttpd

I currently am using lighttpd (1.5.0 SVN) to serve large concurrent downloads (FLV files). However, I've noticed a strange situation where after some time (up to 24 hours) the server will get into a situation where all connections will terminate with the error like this:

2007-05-10 01:11:14: (server.c.735) NOTE: a request for /2451/1178731120-TALRAW.flv timed out after writing 493971 bytes. We waited 600 seconds. If this a problem increase server.max-write-idle
server.c.744: (trace) (timeout)

This will happen begin to happen to most of the files being downloaded.

I have attached a partial copy of the error.log and also my configuration. Please let me know what else I can do to help determine the cause of this. Thanks much.
