As it turns out, the problem is the way the switch closes the connection at the end of the file transfer. Apparently, Net::SCP::Expect doesn't expect (pardon the pun) the string it gets. So here's the code I'm using (successfully, so far) in the production script to handle it:

sub scp_errors {
        use strict;

        my $line = shift;

        if ( $line =~ /Connection.+closed by remote host/ ) {
                # This is expected from an 8600.
                return(0);
        } else {
                # Get rid of CR and LF.
                $line =~ s/\012//g;
                $line =~ s/\015//g;
                print "Got error pulling file:\n";
                print "\t", $line;
                print "\n";
                return(1);
        }
}

As far as I can tell, only one error line gets passed to the error handler. If this turns out not to be the case later, I'll have to change scp_errors to deal with multiple args.
