I'm having trouble with Varnish, it works for a couple of views and then just goes sick... The weird thing is that it does work for about 20 or 30 requests. If I call apache directly it works fine. I'm running Varnish Version: 3.0.3-1 on Debian Squeeze and, for now, Apache on port 80 and Varnish on port 8080 on the same server..

I'm using https://github.com/mattiasgeniar/varnish-3.0-configuration-templates as base for my VCLs and modified the VCLs to support Concrete5.

Anyone any clue on how I should debug this?

backend default {
    .host = "127.0.0.1";
    .port = "80";
    .connect_timeout = 1.5s; 
    .first_byte_timeout = 45s; 
    .between_bytes_timeout = 30s; 
    .probe = {
        .url = "/";
        .timeout  = 1s;
        .interval = 10s;
        .window    = 10;
        .threshold = 8;
    }
}
