The problem is basically, everything works fine, but periodically the interface "hangs" (tcpdump shows no frames). A reboot or an ifconfig down followed by an ifconfig up fixes the problem for some time. Traffic peaks at maybe 20mbit per day and its all 802.1Q VLAN tagged traffic (about 10 vlan interfaces). When this happens netstat reports only errors and no packets on the affected interface. Media is set to autoselect. This is happening about 5-10x per day. Heres relevant sysctl and ifconfig info. dev.em.6.%desc: Intel(R) PRO/1000 Network Connection 6.9.14 dev.em.6.%driver: em dev.em.6.%location: slot=3 function=0 dev.em.6.%pnpinfo: vendor=0x8086 device=0x1079 subvendor=0x8086 subdevice=0x1179 class=0x020000 dev.em.6.%parent: pci3 dev.em.6.debug: -1 dev.em.6.stats: -1 dev.em.6.rx_int_delay: 0 dev.em.6.tx_int_delay: 66 dev.em.6.rx_abs_int_delay: 66 dev.em.6.tx_abs_int_delay: 66 dev.em.6.rx_processing_limit: 100 em6: flags=8843 metric 0 mtu 1500 options=9b ether 00:04:23:cd:47:82 media: Ethernet autoselect (1000baseT ) status: active On Tue, Jan 5, 2010 at 6:35 PM, Jason Chambers wrote: > Hiroki Sato wrote: > > Thank you!
