this is the first time I wanted to cache FastCGI responses from the
upstream servers. I have set up everything like in the documentation
examples but I got

Reloading nginx configuration: [emerg]: the size 10485760 of shared
memory zone "obrazek"
conflicts with already  declared size 0 in /etc/nginx/nginx.conf:41 
configuration file /etc/nginx/nginx.conf test failed

on nginx reload. It does not say where the first occurence of this
memory zone is. I have grepped all my configs but this line 41 is the
only occurrence. I'm using nginx 0.8.50. I noticed there were some
directories /var/lib/nginx/fastcgi with the fastcgi_cache two level
structure already before I turned on this directive. I guessed there
were created by the Ubuntu package. I redirected the fastcgi_cache_path
to another location, yet to no avail.
