Net::Telnet - problem with very large buffer

Wondering whether anyone has encountered and solved this problem:

I'm using Net::Telnet to collect output from a CLI. It has worked
perfectly for more than a year and a half -- until now.

The command in question produces at least a 1,000 lines of output.
What's strange is absolutely all of the output is in the input_log,
but I cannot get a single character from getline().

Any thoughts / remedies?

Code below:

  $self->{'telnet'}->input_log('/tmp/telnet.in');

  @screen = $self->{'telnet'}->cmd(-string=>$cmd_str,
                                   -cmd_remove_mode=>1,
                                   -prompt=>$self->cli_prompt_str,
                                   -timeout=>90,
                                  );

  # If screen array has only one element
  # that is the empty string,
  # try to drain socket another way

  if ( !(@screen) || ((@screen == 1) && !($screen[0])) ) {
      $self->log('Warning: No data in buffer...');
      while ( (my $line = $self->{'telnet'}->getline(-timeout=>15)) )
{
        push(@screen, $line);
      }
  }

Again, '/tmp/telnet.in' has all of the data that I expect from the
command, but neither cmd() nor getline() seems able to retrieve data.

Am I blowing up Net::Telnet's internal buffer with the large result
set?

PM
