Hello.
I've got a production server which keeps crashing if I use bpfs to much.
I usually only use bpf0 for dhcp server, but if I start e.g. snort and ntop, the machine will soon reboot. The same
happens if I run tcpdump.
uname -a gives:
FreeBSD xxxxx.yyyyyyyy.zz 4.7-RELEASE-p9 FreeBSD 4.7-RELEASE-p9 #2: Sat Mar 22 19:25:28 CET 2003
root@xxxxx.yyyyyyyy.zz:/usr/obj/usr/src/sys/XXXXX i386
The hardware is an Athlon with 128MB RAM, 4 SCSI HD building two mirrored vinum volumes and two Intel NIC (one of which
is currently unused, but was when it all began and probably will be again soon).
The problem has started to show after an upgrade to 4.6 or 4.7 I believe (but I cannot recall exactly).
I might as well try an upgrade to 4.8, but I'd rather have more insight.
Following is the output of bt from gdb. Anyone can suggest where do I look next?
