There are a lot of PHP-FPM crashes in de PHP-FPM log… Take a look in the changelog of the lastest PHP version: [http://php.net/ChangeLog-5.php](http://php.net/ChangeLog-5.php) There are a few PHP-FPM related bugs fixed. > ``` > default_type application/octet-stream; > client_header_timeout 10; > gzip_proxied any; > listen 8080; > # W3 Total Cache > fastcgi_pass 127.0.0.1:9000; > > pm.max_spare_servers = 3 > [23-Jul-2012 08:13:26] NOTICE: ready to handle connections > [23-Jul-2012 08:41:05] NOTICE: exiting, bye-bye! > > ``` > > signal 11 (SIGSEGV) after 601.533647 seconds from start > > * * * > > nginx mailing list > removed\_email\_address@domain.invalid > [nginx Info Page](http://mailman.nginx.org/mailman/listinfo/nginx) – Augusto Mecking Caringi ---

How the Nginx ↔ PHP-FPM connection is made? – Augusto Mecking Caringi ---
