If your machine has more than 64Mb, you need to tell your kernel in
your config file:
option          EXTMEM_SIZE=96000       # size of extended memory -- 96Mb

This is the line i have in my machine.

I don't know why you see those messages, but there is a good chance
they'll go away when you recompile your kernel to see all the memory
(btw, the message means that you run out of mbuf clusters as far as i
can tell).
