Your default sub gets called when no other action matches. If you are 
using subreq in default and getting deep recursion, it could be because 
no action matches the uri in your call to $c->subreq():

sub default {
	my ( $self, $c ) = @_;
	# subreq ends up here too
	$c->res->{body} = $c->subreq('non_existent_action');
}

Try commenting out your call to $c->subreq() and see what happens when 
you enter the uri you're passing to $c->subreq in the browser instead.
