I have an e-commerce site with 300,000 products and 20,000 categories. It is slow and currently in production. I decided to install Varnish to speed up. The trouble is that during installation, I got a Guru Meditation.

Since the site is in production, I am not allowed to leave this error more than a second, thinking to have made an enormous stupidity.

I followed the following tutorial: http://www.euperia.com/linux/setting-up-varnish-with-apache-tutorial

I'm sure I followed all without error.

I say that there may be a specific configuration with plesk.

Has anyone already installed Varnish on a ubuntu 10.04 server with plesk 10? Does anyone have a better resource?

I know it is "very vague" as an error, but maybe some of you have had this problem.

Sincerely,
