^^^^^^^^^^^^^^
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.

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:

Yepp.. that sure sounds like the 3.4R if reference counter problem, usually
right after a big flash update from one of your BGP peers.
