I'm using c3640-js-mz.122-28 witch is GD. Now my router is functionning
well, but with the input queue is always 1809 and no traffic in tunnel
interfaces (used for backup purposes).
There is no recursive routing in my routers and no loops as I checked.

Objet : RE: input queue increasing
I seem to recall a bug a while back that malformed packets could fill up
the input queue and stop the router from processing IP Input. Are you
running a deferred release? If so check the release notes to see why it
was deferred.
