Description of problem:
This error occurs when mpd starts with systemctl
SELinux is preventing mpd from using the 'execstack' accesses on a process.

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

If you believe that mpd should be allowed execstack access on processes labeled mpd_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:
# ausearch -c 'mpd' --raw | audit2allow -M my-mpd
# semodule -X 300 -i my-mpd.pp
