Lighttpd

Hi, I have been running lighttpd on my server for a few days now and I'm seeing a lot of these messages in error.log:

2008-02-09 23:54:16: (server.c.1253) NOTE: a request for /files/psp/pspirshell39public.zip timed out after writing 43440 bytes. We waited 360 seconds. If this a problem increase server.max-write-idle

I'm seeing 100s of these logged a day. Should I be worried about this error and if not is there anyway to prevent lighttpd from logging it?
