Description of problem:
idk what is wrong with this program
SELinux is preventing /usr/lib/systemd/systemd-oomd from 'watch' accesses on the sock_file /run/dbus/system_bus_socket.

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

Si cree que de manera predeterminada se debería permitir a systemd-oomd el acceso watch sobre  system_bus_socket sock_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 'systemd-oomd' --raw | audit2allow -M mi-systemdoomd
# semodule -X 300 -i mi-systemdoomd.pp
