Well, just letting some time elapse in order to ensure that all the data has arrived is not a reliable approach.

Is there any reason for setting the connection in non-blocking mode?

In any case, you can try using Net::SSH::Any instead of Net::SSH2. It can run on top of Net::SSH2 and provides a higher API, making most tasks easier to accomplish. For instance: 

use Net::SSH::Any;
my $ssh = Net::SSH::Any->new($ipaddr, user => username, password => $p
+assword);
$ssh->error and die "Unable to connect to $ipaddr: " . $ssh->error;
my @lines = $ssh->capture('/nas/sbin/getreason');
for (@lines) {
  next if /10 - slot_0 primary control station/;
  if (/contacted$/) {
    print $mailfh "DM is OK: $_\n";
  }
  else {
    print $mailfh "POSSIBLE DM FAILURE:Please check $ipname ($ipaddr):
+ $_ POSSIBLE DM FAILURE:\n";
  }
}
