It takes full routes off an ATM ^^^^^^^^^^^^^^ Upgrade to 3.4-Stable, the reference count of your network interface is wrapping past the 16 bit limit of a short and probably the cause of your panic. > OC3 (hea0 set up as atm1) and routes packets between that and the 100mbps > Ethernet port. Also I hope you have tweaked up your KVM space, full routes take a fair bit of kernel virtual memory space to hold. I usually run with 48M of kvm, some times 64M on full feed BGP boxes, I can say it does work fine on 3.4-stable, and that I had nothing but regular panics on 3.4-Release and for a long time after that: br1.CN85pm.abtltd.com# uname -a FreeBSD br1.CN85pm.abtltd.com 3.4-STABLE FreeBSD 3.4-STABLE #0: Mon Jan 3 02:40:43 PST 2000 root@br1.CN85pm.abtltd.com:/usr/src/sys/compile/BR1 i386 br1.CN85pm.abtltd.com# netstat -rn | wc 77695 468055 5444199 > I'm getting periodic (every few days) crashes.
