如何在CentOS中生成coredump（php-fpm）

Question

I have this setting in www.conf (php-fpm): rlimit_core = unlimited

Also I have this command:

ulimit -c unlimited

and my setting is:

# cat /proc/sys/kernel/core_pattern
/tmp/core-%e-%s-%u-%g-%p-%t
# cat /proc/sys/kernel/core_uses_pid
1

In error.log I have:

child 26279 exited on signal 11 (SIGSEGV - core dumped) after 522.834434 seconds from start

It tells me that a core was dumped, but I didn't find coredump in /tmp

How can I generate coredump file and find it?
