I am using RH 7.3 with the 2.4.20 kernel. It doen't have the patch. But I don't need it at the moment. I need to figure out why my /proc/mounts file is filling up with the same mount points.

My problem is a NetApp. Not because it's a NetApp, rather I believe it's the way volumes are exported.
> showmount -e fs7
Export list for fs7:
/vol/vol0/systems   (everyone)
/vol/vol0/muse      (everyone)
/vol/vol0/avidcache (everyone)
/vol/vol0           (everyone)

What I see in /proc/mounts:
fs7:/vol/vol0/muse /nfs/hosts3/fs7/vol/vol0/muse nfs rw,v2,rsize=8192,wsize=8192,hard,intr,udp,lock,addr=fs7 0 0
fs7:/vol/vol0/avidcache /nfs/hosts3/fs7/vol/vol0/avidcache nfs rw,v2,rsize=8192,wsize=8192,hard,intr,udp,lock,addr=fs7 0 0
fs7:/vol/vol0/systems /nfs/hosts3/fs7/vol/vol0/systems nfs rw,v2,rsize=8192,wsize=8192,hard,intr,udp,lock,addr=fs7 0 0

But I don't see:
/vol/vol0

I believe autofs is expiring and unmounting fs7:/vol/vol0 and getting confused as what to do with the directories under that root vol.

Any ideas what 'mount table full' means?

Everything works fine after a reboot.

      
It means that you have more than 256 mounts that don't have a 
block-device back-end.  These include NFS, autofs, procfs, sysfs...

This is a known limitation in linux 2.4.  You may want to try a patch 
like the following:

http://people.redhat.com/zaitcev/linux/linux-2.4.19-pre7-unmaj.diff


    

Most of the RedHat packaged kernels have this patch.

What distro are you using?
What version of autofs?
