Well, for reading directories and a few small files the recently posted
patch to originate NFS mounts and NFS requests from a privileged port
worked quite well.  However, when I mounted a SUN disk on my 386BSD box
as follows:

      ifconfig ...
      route ...
      mount -t nfs -o soft neuro:/home/neuro2 /home/neuro2

and then pressed the system quite hard:

      tar cvf xxx.tar /home/neuro2/merlin

the kernel panics with 'panic: kmem-malloc: kmem-map too small' after
only about half a megabyte is transferred.  

The system doesn't have a problem with editing individual files and/or
something like:

      ls -lisaR /home/neuro/merlin

where there are a couple of hundred megabytes and hundreds of files.

Does anyone have any insight into or fix for this problem?

Thanks, AJ
