panic in netisr (I think) + DUMP FAILED (ERROR 6)

Hi

I finally hooked up a console to this machine because its dumps
have been broken or corrupted for many months.  Sadly there isn't
much more infonmation than this console capture.

** DUMP FAILED (ERROR 6) **

I'm not sure why the dump failed - there's more than enough space
in the swap partition for all memory:

[firewall2.jnb1] /usr/src # swapinfo -h
Device          1K-blocks     Used    Avail Capacity
/dev/mfid0s1b    25165824       0B      24G     0%
