This was not happening with -RELEASE. I upgraded on the advice that STABLE would decrease the %cpu spent in system, which was much higher than that spent in user. The machine's only fucntion is as a reverse proxy (2 separate squid processes to take advante of both cpus). Let me know if a dump would be helpful, or if there's anything I can do to help. Dual AMD Opteron system.. Jeff ps. I don't believe the problem is with a zebra/ospfd kernel interaction. the open port RST responses are expected; i can explain why if it would provide insight into the problem... www2.cdn.sjc#uname -a FreeBSD www 5.3-STABLE FreeBSD 5.3-STABLE #2: Sun Dec 5 21:06:14 PST 2004 root@www2.cdn.sjc:/usr/obj/usr/src/sys/SMP amd64 FreeBSD/amd64 (www2.cdn.sjc) (ttyd0) login: Dec 6 13:03:37 www2 ospfd[18772]: old umask 23 127 Limiting open port RST response from 518 to 200 packets/sec Limiting open port RST response from 318 to 200 packets/sec Limiting open port RST response from 264 to 200 packets/sec Limiting open port RST response from 206 to 200 packets/sec Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 01 fault virtual address = 0x18 fault code = supervisor read, page not present instruction pointer = 0x8:0xffffffff803a14b3 stack pointer = 0x10:0xffffffffb1bd9800 frame pointer = 0x10:0x0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 44 (swi1: net) trap number = 12 panic: page fault cpuid = 1 boot() called on cpu#0 Uptime: 23m44s Cannot dump.
