SELinux is preventing abrt-dump-journ from 'write' accesses on the sock_file io.systemd.Machine.

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

If you believe that abrt-dump-journ should be allowed write access on the io.systemd.Machine sock_file 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 'abrt-dump-journ' --raw | audit2allow -M my-abrtdumpjourn
# semodule -X 300 -i my-abrtdumpjourn.pp
