I've got a perl script here that uses IPC::Shareable to store an array that is generated using parallel::Forkmanager. I am able to write data into the array fine 500 - 11000 lines and all works well but when I try reading from the array I always receive an out of memory error even though nothing is writing to shared memory only reading from it. Has anyone come across this before and if so how was it solved ? My code is as follows...

tie @$output, 'IPC::Shareable', $glue, { %options } || die "Tie failed
+\n";
my $pm=new Parallel::ForkManager(50);
foreach $keyword ( @keywords ) {
    $pm->start and next;
    $key= join('\+', split(/\ /, $keyword));
    $remote = IO::Socket::INET->new( Proto     => "tcp",
                                     PeerAddr  => $host,
                                     PeerPort  => $port,
                                   );
    unless ($remote) { die "cannot connect to http daemon on $host on 
+$port" }
    $remote->autoflush(1);
    print $remote "GET $prefix$key HTTP/1.0" . $BLANK;
    $count="0";
    while ( <$remote> ) { 
        if (/flist/i) {
            $count++;
        }
    }
    push (@$output, "$keyword,$count");
      close $remote;
    $pm->finish();
}
$pm->wait_all_children;

# Write message to tmp file.
$tempfile = basename($file);
$tmpfile = "/tmp/$tempfile";
open(TMPFILE, ">$tmpfile") || die "Can't open $tmpfile for writing";
foreach $line ( @$output ) {
    $count++;
    print "$count\n";
    print "$line\n";
    print TMPFILE "$line\n";
}
}
close(TMPFILE);
