glad I found you here....

I have PHP-FPM config with 20 child processes, 6 to start with, 6 as backup, and rest for use. The problem is when the system reaches 16000 concurrent users, almost 6 of child processes goes zombie, and I have to kill it manually.... right now I have set some cron job to deal with it, but thats not the good solution. Can you help me fix this ? I can send you my debug log, if you are interested !!!

which version of php is running? is eaccelerator or apc extension enabled? what does the fpm log say?

I use APC 1.3.9 with PHP 5.4.6

The Log doesn't give much information, it says child process killed, thats all... I have been trying this out in other tech forums too...

Part of the logs from yesterday http://pastebin.com/3s7MNPer
The PHP-FPM configuration http://pastebin.com/0yUgDJcu

I'm on Ubuntu 12.10 32 bit server....

I see some "child xxxxx exited on signal 11" which mean segment faults.
Here is a bug report about segfault on PHP 5.4.6+APC 3.1.13 : https://bugs.php.net/bug.php?id=63005
Maybe you can try upgrading APC to version 3.1.14.
