I am using Parallel::ForkManage. While running run_on_finish, I am checking what is the return code of the Child Process. Now, in child process i am running curl to download a file. While downloading some times the remote server goes down and curl terminates in between. Now, when this happens and I check the return exit code in run_on_finish, it is coming as zero while when i reproduce this same thing on shell prompt, it returns me error code ($? to be 175 or a non zero). Can you help me trap correct error code in run_on_finish? Here is my code: 
$pm->run_on_finish (
    sub {
        my ($pid, $exit_code, $ident, $signal, $core) = @_;
        if ($core) {
            #If there is a core, report it
            print "Process $pid dumped core\n";
        } else {
            #Collecting process info in Hash to be reported at the end
+ of script.
            #print "Process $pid executed successfully\n";
        }
        $pidInfoHash{$pid} = $exit_code;
    }
);

for (1..$total_calls/$cps) {
    for (1..$cps) {
        my $pid = $pm->start and next;
        RunChild();
        $pm->finish;
    }
    sleep(1);
}

sub RunChild {
    if (defined $proxy) {
        $ENV{http_proxy}="$proxy";
    }

    $logFile = $logDir."/header_".$call;
    `curl -o /dev/null -m 222 \"$Link\" 2>> $logFile`;
    my $curlResult = `echo $?`;
    chomp($curlResult);
    if ($curlResult != 0) {
        print "Curl Result $curlResult :: Call Drop : $callDrop\n";
        $callDrop++;
        print "Curl Result $curlResult :: Call Drop : $callDrop\n";
    }
}
