Description of problem:
When you enable slow logs in PHP-FPM, you get a ton of errors regarding ptrace. 

Version-Release number of selected component (if applicable):
3.7.19-279

How reproducible:
Junst enable slowlogs in /etc/php-fpm.d/www.conf

slowlog = /var/log/php-fpm/www-slow.log
request_slowlog_timeout = 5s

Here's a policy that works for me. I think it should be corrected and included into mainstream. Slow logs are very important and should be allowed. Maybe creating a boolean for this?

module php-fpm-slow_logs 1.0;

require {
    type httpd_t;
    class capability sys_ptrace;
    class process ptrace;
}

#============= httpd_t ==============
allow httpd_t self:capability sys_ptrace;
allow httpd_t self:process ptrace;
