Strange Samba problem

[Lars Friend <lfriend%mcci.com@localhost>]

Hi All,

	I am having a strange problem with Samba.  I built and installed 
Samba 3.0.26a from pkgsrc on a NetBSD 3.1 machine (running the stock 
release GENERIC kernel), and for the most part it works fine, except 
for one thing:

If I connect up and browse all shares (like going to \\net9vm\ in an 
explorer window on an XP box), it displays them all fine, and I can 
connect and use them as expected, but I noticed that every time I 
connect and browse like that, something like this appears in the 
/var/log/log.smbd file:

Has anybody else seen this?  The link included in the error message 
tells me I ought to trace through it with GDB and see what gives, but 
before doing that, I want to be sure I'm not reinventing the wheel...

An additional possible detail, all of the directories that are served 
out by Samba are remote, and mounted as needed via nfs by amd.

        Thanks much,
                -lars
