I have seen exactly this happen when exporting an NFS area from a sunos
system to a FreeBSD system that had an ethernet card that only contained 8K
of RAM --- maybe this is what is happening with your systems. To fix it,
you need to add an option in the sunos /etc/exports to limit packet size
(unfortunately, I can't look up the option right now).
I believe that you get the effect you mentioned because a directory listing
is a small amount of data that gets transferred OK while large amounts of
data cause overflows to occur in the network card, causing loss. I found
NE2000 clone cards with 16K of RAM to be OK.
