Description of problem:
SELinux is preventing php-fpm from 'map' accesses on the archivo /dev/shm/mongoc-934.

*****  Plugin catchall (100. confidence) suggests   **************************

Si cree que de manera predeterminada se debería permitir a php-fpm el acceso map sobre  mongoc-934 file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso temporalmente ejecutando:
# ausearch -c 'php-fpm' --raw | audit2allow -M mi-phpfpm
# semodule -X 300 -i mi-phpfpm.pp
