[drupal-support] Critical problem

[Abalieno]

My site is dying with some problems to the tracking of referrers:

This spamming for various pages. Which brings to:

Tue Mar 22 19:09:57 2005] [error] [client 66.27.100.241] (12)Cannot allocate 
memory: couldn't create child process: 12: php-script

Then the site dies for about two hours. I find this strange because it 
doesn't lag at all before dying so it doesn't seem simply a crash due to 
usage. It can be something messing with the referrers? And there's a way to 
disable temporarly that part?
