I wrote an automated FTP script as follows:
#!/usr/bin/perl -w
use strict;
use Socket;
use Net::FTP;

$site = 'ftp.wolfger.com';
$address = inet_ntoa(inet_aton($site)));
$ftp = Net::FTP->new
(
    "ftp.wolfger.com",
    Timeout => 60
) or die "Connection failed to $address\n";

$user = "<insert username here>";
$pass = "<insert password here>";
$ftp->login($user, $pass)
    or die "Login failed for $user.\n";

$ftp->cwd('./main_html');
$ftp->type('binary');

$local  = "/home/wolfger/Shared/Documents/wolfger/howllog.html";
$remote = "howllog.html";

$ftp->put($local, $remote)
     or die "Failed to put file $remote.\n";

$ftp->quit()
    or die "Could not quit connection to $address\n";

[download]

The problem is that sometimes this works fine. Other times, it dies with the message "Failed to put file howllog.html." I'm at a complete loss for why it sometimes works and sometimes doesn't. One thing I do notice is that after the script is run, I have the following process running on my box:
postfix 18788 1591 0 15:58 ? 00:00:00 pickup -l -t fifo -u -c

Usually killing this process allows the script to work again, but this morning I got not get the script to run successfully at all.

Edit: Added <code> tags. larsen
