I'm having the same thing. Hopefully Matt comes up with a fix soon.

I spent the last two days working Peter Avalos's machine which
    (when we turned on mbuf debugging) was having the same issue.

I think I finally cracked it, and pushed the fix to the udp6 code.
    It took a long time to find the bug.

The first nameserver entry in resolv.conf was an inet6 address, which is
consistent with the early crash.

Anyway, I confirm it doesn't crash anymore on my machine. Thanks :)

Let it run for a bit...I'm seeing strange behavior after about an hour.

Do you have any example ?

I have seen strange things ever since I upgraded to 2.7.

After some time, keyboard leds don't change state under Xorg for example.
Web sites on slow hosts / different continents have a tendency to not load
completely the first time; the browser tab/window just spins with 100% CPU
and never timeouts.

But these are not specific to this last mbuf issue.

This is fixed for me. How about you?

Same thing here. I think this one can be closed.
