Hi, I have a script which spawns 5 parallel processes. This script runs correctly when I use it but when another user tries to run it, it starts correctly but in couple of seconds, 2 processes exit and remaining 3 processes continue running as normal. What can be the reason for this? Addition: Below script is not the script itself. I just wanted to show the part processes created. In real script, each process takes couple of hours to finish. 2 exiting processes don't touch files in the script when different user tries to run it. Simplified script is below, 
#!/usr/bin/env perl
for($i = 1; $i < 6; $i++){
   my $pid = fork();
   if($pid){
      print "INFO\t: Started job $i (PID: $pid)\n";
      push @childs, $pid;
   }elsif($pid == 0){
      pJob($i);
      exit 0;
   }else{
      die "ERROR\t: Can not fork:$!\n";
   }
}

for(@childs){
   my $tmp = waitpid($_, 0);
}

sub pJob($){
   my $id = shift;
   `touch /tmp/file_$id`;
   print "INFO\t: Done with job $i\n";
}
