I'm running Centos 7 with php-fpm 5.4. I'm encountering a (signal 11) SIGSEGV error in my php-fpm error logs and want to debug it.
I've followed the advice of php5 fpm: how do you generate core dump from segfault? but php-fpm is still not even attempting to generate core dumps. From the php-fpm error log:
WARNING: [pool website.com] child 26953 exited on signal 11 (SIGSEGV) after 0.931337 seconds from start
If a core dump had been generated, it would read
(SEGSEGV - core dumped) but it doesn't.
