You DA MAN, Charles! It exists, owned by root, created when the machine
was last booted, is empty and is currently locked. One of the other,
non-problematic, servers has a similar empty /net directory; the other
doesn't.
AND, I should add, the other two servers were NOT running autofs. In fact, autofs wasn't even installed on one of the
other servers. So on the non-problematic server with a /net directory, it's just an empty directory. I'm totally
convinced that autofs was causing the 3-second delays on stat64 /net/* calls.
So the answer to our old question "what's different about the problematic server?" is "it's running autofs, which is
creating and locking /net". (I've now uninstalled autofs on all servers.)
