Hi McA,

I had a developer colleague of mine help me on writing below fork code (after following your advice).

#!/usr/bin/perl -w
use strict;
use POSIX;

my @list=("server1","server2","server3","server4","server5","server6",
+"server7","server8");
my $count = 0;
my $pcount = 5;

foreach (@list)
{
    chomp ;
    my $real_host = $_;
    if( (my $pid = fork()) == 0)
    {
        print "Processing - $_ \n";
        my $wait=ceil(rand(10));
        print "Wait:$wait \n";
        sleep($wait);
        print "Exit Status= $? \n";
        if($? ==0)
        {
            print "$_ Exit successfully \n";
        }
        else
        {
            print "$_ Does not Exit successfully \n";
        }
        print "Completing - $_ \n";
        exit;
    }
    $count++;
    while($count >= $pcount)
    {
        wait();
        $count--;
    }
}

while(wait() != -1){}

I still don’t understand few parts of this code but I am OK with that. This test code is working perfectly. So I am planning to use the same logic in my orchestrator.

Many thanks for your help.
