My 1.2.1 SS20 has been getting a rash of these suckers as of late, and sure
enough, "netstat -m" says why:

netbsd4me:1:440 % netstat -m
1174 mbufs in use:
        1098 mbufs allocated to data
        63 mbufs allocated to packet headers
        13 mbufs allocated to socket names and addresses
511/512 mapped pages in use
1170 Kbytes allocated to network (99% in use)
0 requests for memory denied
0 requests for memory delayed
18770685 calls to protocol drain routines

and I can't do an NFS mount to save my life at this point.

Is there some knob I can drop into my kernel config file to get me more
mapped pages for mbufs to use?
