/proc/mounts inconsistency? (2.0.30+autofs)

[Steve Dunham]

Are entried in /proc/mounts supposed to be repeated? I'm seeing the
following:

# mount |wc -l
     17
# wc -l /proc/mounts
     34

I see a few entries that are repeated (one is repeated 4 times), and
some that are not listed by mount.

Also, is there an upper limit to the number of NFS filesystems that
are mounted? If so, is there any way to change this?

The reason I'm asking is that we recently moved our Samba server from
a Sun to a Intel Linux box because of locking problems, and it seemed
to be running out of mountpoints (according to the rather ambiguous
mount error message).

We updated the automount daemon (from 0.3.7->0.3.14), which _seemed_
to alleviate the problem, but the difference between mount and
/proc/mounts has been gradually increasing over the last day.
