Strange error of current write on NFS

[Peng Yu <pengyu.ut@xxxxxxxxx>]

Hi,

I have the following perl script that write to a nfs system. The
output doesn't have all the number from 1 to 10. But if I try the
program on a local disk, I see all the number from 1 to 10.

I'm not sure if this is an NFS problem (It may be a perl problem).
Could any guru here let me know if this is possible due to an NFS
problem?

$ cat main.pl
#!/usr/bin/env perl

use strict;
use warnings;

use Parallel::ForkManager;

open OUT, ">main.txt";

my $pm = new Parallel::ForkManager(5);

foreach my $n (1..10) {
  my $pid = $pm->start and next;
  print $n, "\n";
  sleep rand(1);
  print OUT $n;
  $pm->finish;
}

$pm->wait_all_children;

$ ./main.pl

$ cat main.txt
