Hmmm...problem with pgp?

-------Order.pm-----
sub pgp_encrypt {
	my($body, $key, $cmd) = @_;
	$cmd = $Vend::Cfg->{PGP} unless $cmd;
	if($key) {
		$cmd =~ s/%%/:~PERCENT~:/g;
		$cmd =~ s/%s/$key/g;
		$cmd =~ s/:~PERCENT~:/%/g;
	}
	my $fpre = $Vend::Cfg->{ScratchDir} . "/pgp.$$";
	open(Vend::Order::PGP, "|$cmd >$fpre.out 2>$fpre.err")
			or die "Couldn't fork: $!";
	print Vend::Order::PGP $body;
-------Order.pm-----

-------ValidCC.pm----
		# Encrypt the string, but key on arg line will be exposed
		# to ps(1) for systems that allow it
		open(CRYPT, "$cmd |") || die "Couldn't fork: $!\n";
		chomp($encrypted = <CRYPT>);
		close CRYPT;
		$status = $?;
	}
	else {
		$cmd = "| $cmd " if $cmd;
		open(CRYPT, "$cmd>$tempfile ") || die "Couldn't fork: $!\n";

Or did you get a message like "Hammered session lock <lockname> left by
PID <PID number>"?
--------snipp--------
			if ( $left > $Global::HammerLock ) {
--------snipp--------
and
--------snipp--------
    ['HammerLock',		 'integer',     	 30],
--------snipp--------
