Actually, that looks more like you are just doing a direct NFS mount. 
Autofs (automounter) is a process in which the system will automatically
mount a file system as you access it, providing that information is in
the main database (be it within NIS (yp), LDAP, or some other back end),
and it will automatically *unmount* that file system after a set period
of time of inactivity.

Not too familiar with Debian myself so I don't know what NFS version it
supports.  I see that you are forcing it to NFSv2 (v2 is UDP-only),
using a soft mount (allowing for a timeout of access to the volume
before returning an I/O error), disabling all file attribute caching
(for performance), forcing read/write to 8MB chunks (default), and I
don't believe the "auto" option does anything.

One thing to try is to just use the defaults for the mount and see if
that helps.  If it does, then slowly introduce each of the options to
see which one is the culprit.

I run with the defaults, mostly.  I just specify "actimeo=0".
