Igor,
While I have your attention, is there a better way to write status blocks than the following? I figure this would be useful information for everyone.
error_page 500 502 503 504 /500.html; location = /500.html { expires 5d; root /var/www/crm; }
error_page 404 /404/index.php; location = /404/index.php { expires 5d; root /var/www/crm; }
