i'm not 100% certain that i completely understand the
problem that you are seeing, however i've done my share of
wrestling with net::snmp. the one bit of advice that i would
give you, is that perhaps rather than testing on whether
$response is defined, you may want to test on if $error exists.
i generally make a seperate call to grab the error return
if it exists
my $session = Net::SNMP->session ( ... );
my $error = $session->error;
perhaps a next if ($error); or just test on $error's
existance, rather than checking if $session is defined?
humbly -c
