Bug description:FPM+chroot: random Error 404

Debian squeze:

Lighty 1.4.28 with fastcgi config lines:

# ls -l /web/web/host/web/web/host
lrwxrwxrwx 1 root root 1 Apr 26 15:10 /web/web/host/web/web/host -> /
Docroot is:
/web/web/host/teszdomain.hu/pages
If I turn on chroot to /web/web/host in the fpm config, PHP starts dropping
error 404 randomly:

Note, I run PHP-FPM with the same chroot+symlink trick on other box and it
works fine all the time.
