[squid-users] help with squid redirectors

Greetings everyone,

So I'm having trouble with my squid proxy-cache server. I recently added
a redirect program because I had to make users go to my kaspersky admin
kit and my WSUS services to get their updates and it works fine but I
get constantly a warning and squid just collapses after a few minutes of
run time. This is what I get in my cache.log:

2011/03/07 15:54:17| WARNING: All url_rewriter processes are busy.

Squid Cache (Version 2.7.STABLE7): Terminated abnormally.

This is what I have in the squid.conf

# TAG: url_rewrite_program
url_rewrite_program /etc/squid/redirect

# TAG: url_rewrite_children
url_rewrite_children 100

# TAG: url_rewrite_concurrency
url_rewrite_concurrency 50

# TAG: url_rewrite_access
url_rewrite_access allow redirect

And this is what I have in my redirector script

#!/usr/bin/perl
BEGIN {$|=1}
while (<>) {
     @X = split;
     $url = $X[0];
     if ($url =~ /^http:\/\/dnl(.*)kaspersky(.*)com(.*)/) {
          print "301:ftp:\/\/dnl-kaspersky\.quimefa\.cu\:2122\/Updates";
     }
     elsif ($url =~ /^http:\/\/(.*)windowsupdate(.*)/) {
          print "301:http:\/\/windowsupdate\.quimefa\.cu\:8530";
     }
}

Can you please help me to solve this?
