HTTP headers: x_csize: 0 with sitemap generator 8 on PHP 5.3

I'm getting this error when I'm trying to run the sitemap crawl with Sitemap Generator V8:

There was an error while retrieving the URL specified: [ External links are visible to forum administrators only ]
HTTP Code:

HTTP headers:
x_csize: 0

HTTP output:

I've selected the debug output option but have nothing to work with? I've also tried using curl but get the exact same error.

Thanks
