Hello. We have a problem with FreeBSD 9 stable (currently on r267070) as PPPoE BRAS by mpd 5.7. Server catches 1-3 kernel panics every month. Two last core.txt's: http://pkg.hostelnet.ru/pub/dump/core.txt.7.txt (r262224) and http://pkg.hostelnet.ru/pub/dump/core.txt.8.txt (r267070) Now trying to test hint with mpd-down script from similar trhread: http://lists.freebsd.org/pipermail/freebsd-net/2014-June/038952.html Hardware: HP DL360 with Intel 82571EB nic. Average load on server: 150-300 Mbit/s and around 150 users. FreeBSD configuration: running on GENERIC kernel IPFW with few rules (no dummynet, no nat) routing via OSPF (quagga) cat /boot/loader.conf net.isr.maxthreads=2 net.isr.numthreads=2 net.graph.maxdata=65536 net.graph.maxalloc=65536 net.isr.defaultqlimit=4096 net.link.ifqmaxlen=10240 cat /etc/sysctl.conf net.inet.ip.fastforwarding=1 net.inet.ip.redirect=0 kern.random.sys.harvest.ethernet=0 kern.random.sys.harvest.point_to_point=0 kern.random.sys.harvest.interrupt=0 net.inet.raw.maxdgram=16384 net.inet.raw.recvspace=16384 net.inet.ip.intr_queue_maxlen=10240 net.route.netisr_maxqlen=4096 Maybe someone can help to understand: it is a configuration error or a bug MPD/netgraph?
