We used FreeBSD 9-stable (from r259072 to r262224) with 150-300 PPPoE tunnels (mpd 5.7) and it randomly crashing 1-2 times in month. Some times ago one server was rolled back to 8-stable (r259629) - it never crashed since december 2013, while on server with 9-stable already got 8 crash dumps. Both systems have same hardware, GENERIC kernels, same pkgs versions and same configs: /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 /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
