https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193452 Márcio Elias <marcioelias@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |marcioelias@gmail.com --- Comment #2 from Márcio Elias <marcioelias@gmail.com> --- Hi, we get the same problem with same hardware on a 10.3-RELEASE. We get this 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 ISP). The strange is that this error not happens on the time of more load, is random, can occur any time. After change sysctl variables related to network tunning the crashes get less 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=1 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.route.netisr_maxqlen=2048 net.inet.ip.redirect=0 kern.ipc.shmmax=2147483648 And this on the /boot/loader.conf net.link.ifqmaxlen=2048 net.isr.maxthreads=4 net.isr.defaultqlimit=2048 Also we enable LARGE_NAT on /usr/src/sys/contrib/ipfilter/netinet/ip_nat.h. -- You are receiving this mail because: You are the assignee for the bug.
