SELinux is preventing /usr/bin/php from using the 'execstack' accesses on a process.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to allow unconfined executables to make their stack executable.  This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla
Then you must tell SELinux about this by enabling the 'allow_execstack' boolean.
Do
setsebool -P allow_execstack 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you believe that php should be allowed execstack access on processes labeled system_cronjob_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep php /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
