Well that's the issue, the perl program just stops there, no core file, nothing to go on. a sample program: 
#! /usr/local/bin/perl

use Oraperl;
use DBI;
use FileHandle;
use rf;
use IO::Socket;
use IO::Handle;;
use POSIX qw(setsid);

open STDIN, '>/dev/null'   or die "Can't read /dev/null: $!";
print "Step 1\n";
#open STDOUT, '>','/dev/null' or die "Can't write to $prout: $!";
open(STDOUT, '>','/dev/null') or die "Can't write to $prout: $!";
print "Step 2\n";
open STDERR, '>/dev/null' or die "Can't write to $prerr: $!";
#SIG{CHLD} = 'IGNORE';
defined(my $pid = fork)   or die "Can't fork: $!";
exit if $pid;
setsid                    or die "Can't start a new session: $!";
#$SIG{CHLD} = 'DEFAULT';

$logdir = $ENV{out};
$constr = $ENV{CAAO_CSTR};
$user = $ENV{CAAO_USU};
$pass = $ENV{CAAO_PWD};
print"RUN\n";

It only prints Step 1 But when the line is commented, it prints Step 1 Step 2 RUN
