Description of problem:
SELinux is preventing rm from 'unlink' accesses on the archivo .deliver_lock.

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

Si cree que de manera predeterminada se debería permitir a rm el acceso unlink sobre  .deliver_lock 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 'rm' --raw | audit2allow -M mi-rm
# semodule -X 300 -i mi-rm.pp
