It seems to be related to what NIC you have. I have had crashes with fxp (Intel Pro 100MBit) and bge (Broadcom Gigabit) NICs under moderate network load. Removing ipf reduced but did not eliminate the crashes. debug.mpsafe also reduced but did not eliminate the crashes. Another person on the freebsd-amd64 list reported similar network-related crashes until he switched to em (Intel Gigabit Ethernet) NICs. Gary
