If these occur on connections that go over an `IMP' (anything that you
configure with `ifconfig imp0 ...' [or imp1, etc.]), the problem is
most likely the IMP message queue size bug.  This and a whole raft of
other bugs (numbering in the *hundreds*) are fixed in 4.3BSD.

If that is not it, run `netstat -m' to see whether it really is
running out of mbufs (`%d requests for memory denied' should always
be `0').
