Let's see what 'ifconfig -a' says after that happens.

Supposing that there is not an mbuf leak somewhere, you need to increase
NMBCLUSTERS in your kernel configuration and recompile.  See options(4).

(It is too bad that drivers do not ordinarily scale up the length of
their rx rings as the load demands, and share the available mbuf clusters
less greedily.)
