Lighttpd

FreeBSD 4.11 and DragonFlyBSD (enhanced FreeBSD4-derivative). Tried both from ports and manually and always the same. In both cases.

I even tried removing the old rrd file to see if the problem lies there:

2005-03-08 16:08:23: (log.c.67) server started
2005-03-08 16:09:00: (mod_rrdtool.c.217) rrdtool-write: failed Device not configured
2005-03-08 16:09:00: (server.c.790) one of the triggers failed

So no luck. I will try to get some useful truss output (hopefully).

I see the same behaviour with 1.3.13 on FreeBSD 5.3-RELEASE-p2. On al Linux box the same configuration (but without kqueue) works.

-- md

I also encounter this problem here on FreeBSD 5.4-RELEASE-p2.

-- bwolf

To conclude: this only happens for me with freebsd-kqueue.

-- bwolf

I also have this problem on FreeBSD 6-CURRENT, but I have oddly and accidently found that if I run it in the forground with the -D option it works!
