>Description:
Over the past few weeks, I've observed several reboots, which are apparently kernel panics due to something related to zebra.
This machine is a router, and terminates several OpenVPN tunnels as well as IPv6-in-IPv4 tunnels. I'm using Quagga to run OSPFv2 and OSPFv3.
This problem first started in 6.1-RELEASE (box was stable w/6.0), so I upgraded to 6-STABLE, recently, but the problem still persists.
The crash follows:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x78
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc058c693
stack pointer = 0x28:0xdea99a64
frame pointer = 0x28:0xdea99a68
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 1256 (zebra)
trap number = 12
panic: page fault
System info:
FreeBSD 6.2-PRERELEASE (cvs of 6-STABLE from Sept 20, iirc)
quagga-0.99.4_2
I have included the kgdb output, as well as other information about the system, here:
http://www.prolixium.com/share/txt/freebsd/zebra/
I can allow the pf.conf to be viewed, if absolutely needed. It's fairly plain.
Please let me know what else I can provide!
Thanks.
