We get th= is in a Dell R210 II and a T210, both with the same driver loaded, and both running IPNAT to translate a lot o private IP's to Public IP's (we are a IS= P). The strange is that this error not happens on the time of more load, is ran= dom, can occur any time. After change sysctl variables related to network tunning the crashes get le= ss frequent, but the max uptime that we can get is about 2 days. Below is the Sysctl variables that we change. net.bpf.optimize_writers=3D1 kern.random.sys.harvest.ethernet=3D0 kern.random.sys.harvest.point_to_point=3D0 kern.random.sys.harvest.interrupt=3D0 net.inet.raw.maxdgram=3D16384 net.inet.raw.recvspace=3D16384 net.route.netisr_maxqlen=3D2048 net.inet.ip.redirect=3D0 kern.ipc.shmmax=3D2147483648 And this on the /boot/loader.conf net.link.ifqmaxlen=3D2048 net.isr.maxthreads=3D4 net.isr.defaultqlimit=3D2048 Also we enable LARGE_NAT on /usr/src/sys/contrib/ipfilter/netinet/ip_nat.h. --=20 You are receiving this mail because: You are the assignee for the bug.=
