Before running the script below all httpd processes take 1169KB RAM and 9352 SWAP

After one of the http process takes 6292KB RAM and 50,336KB SWAP

Is this normal behaviour?  is there a way to prevent this?


<?php
$a="0123456789";
for($i=0;$i<21;$i++)$a.=$a;
print strlen($a);
unset($a);
?>

Php module config:
configure --enable-track-vars \
                     --with-informix=/usr/products/informix \
                     --with-imap=/usr/products/imap/imap-4.7/c-client \
                     --enable-force-cgi-redirect \
                     --with-apxs=/usr/products/apache1.3.12/bin/apxs

You can use memory_limit to prevent memory over-use.
