Varnish with mod prefork vs mpm worker with mod-fcgid

[nick tailor]

I have heard of others having similar issue with same setup.

Generally they use mpm-prefork or mod fcgi with varnish. I have heard using
Nginx with varnish is the way to go.

What I would do, is disable modfcgi and see if it changes. If it does you
know the problems lies in the settings.

Cheers
