The connections getting reset without application notification is a classic
symptom of a full listen queue. A couple of questions:
Yep thats what I thought.
(1) What FreeBSD version?
7.0-RELEASE-p2 (amd64)
(2) Are you using accept filters?
The modules there but not loaded, so no.
(3) If possibly, are you able to instrument lighthttpd so that you can trigger
it to query SO_LISTENQLIMIT, SO_LISTENQLEN, and SO_LISTENINCQLEN on the
listen socket once things have gone wrong? The respectively (and perhaps
obviously) querye the current administrative limit on queue depth, the
number queue depth on completed connections, and the current queue depth
on incomplete connections. The last of these will only be used with
accept filters on recent FreeBSD network stacks (since the syncache was
added).
Hopefully doing (3) will allow us to try to determine whether it's indeed the
case that somehow the listen queue or event handling has gotten "wedged" in
some way.
This should be possible, I'll have a look, assuming the kgdb stuff doesn't
turn up the required results.

Steve
