I bet you're right.  So theoretically if I figure out how to track down
that lock, it is likely held by my NFS server...

Hrm.  But would it make sense that other smbd processes are apparently
still accessing brlock.tdb OK for different files?

My low level understanding of the locking is lacking a bit. :)

Anyways, I'm guessing if this turns out to be NFS related as we
suspect, the only fix is to _not_ share with NFS. :)
