I have set /proc/sys/kernel/core_pattern with echo /var/cores/core-%e.%p /proc/sys/kernel/core_pattern Then I made /var/cores/ writeable for user www-data and chmodded it with 777. Then sudo service php5-fpm restart and reloaded the page. It crashed but no core was dumped. Why? ulimit is unlimited. By the way, I am on nginx. Your instructions are for Apache.

With these log lines in NGINX: 2013/08/30 01:34:06 [error] 12282#0: *51 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 78.10.247.202, server: binarykitchen.com, request: GET /user/register/action/why/language/de/ HTTP/1.0, upstream: fastcgi://unix:/var/run/php5-fpm.sock:, host: www.binarykitchen.com, referrer: http://www.binarykitchen.com/user/register/action/why/language/de/; There are many of those. Sometimes the page loads, sometimes not. I tried hard to adjust nginx and php-fpm but no success. I am using sockets. Tell me, how can I see what is exactly resetting the connection? Why it is crashing? What commands should I try?
