This appears to be the reply to the nfs readdir request, which is what
would be expected. It could be a problem with the content or the reply
or a NetBSD client issue.

If you were to email me the raw tcpdump capture for the above, I could
take a look at it in wireshark (which knows how to interpret nfs) and
see if there is anything bogus looking in the reply.
("tcpdump -s 0 -w <file> host 192.168.1.1" and then email me <file> as an 
attachment, should do it)
