Hello. I have a FreeBSD machine that tended to hang in the recent past. After a few tests I managed to clearly isolate one condition that causes this kernel panics. If I do a "tcpdump -l -i fxp0" I'm sure the machine will lock in less than 3 second. The same happens (in a more or less short time) if I run ntop, snort or any other thing that opens a bpf. There is a dhcp server running, which is isc version 3.0.1.r11_1 and, on startup, says: >Listening on BPF/fxp0/00:07:e9:0b:78:d9/192.168.101.0/24 >Sending on BPF/fxp0/00:07:e9:0b:78:d9/192.168.101.0/24 So, basically one bpf seems to work. A second one is, however, almost sure death: I didn't have the chance to write down the full exact message yet, but basically it's like "page fault while in kernel mode". uname -a gives: >FreeBSD xxx 4.7-RELEASE-p6 FreeBSD 4.7-RELEASE-p6 #1: Thu Feb 27 1 >2:40:24 CET 2003 root@xxx:/usr/src/sys/compile/XXX i386 Any hint on what I might try to solve this? Has anyone had this problem before? Any way to better debug this? bye & Thanks av. P.S. In case it matters, the machine has two fxp interfaces.
