Lighttpd

I saw something similar last night:

2006-09006 19:43:00: (network_freebsd_sendfile.c.96) writev failed: Socket is not connected 7

The application stopped serving entirely, I had to restart it when I woke up 4 hours later. Please check this out.

This will happen 1-2 times per day.

I'm alsow having this problem with FreeBSD 6.1, what to do?

I tracked the problem down to being PF firewall that kept states of every connection resolving in too many entries for any new connections, adding a QUICK rule resolved it.
