Description of problem:
Problem happend every hours . when system generate new snap and remove old . 
snapper.py from  dnf-plugins-extras-common
/usr/lib/python2.7/site-packages/dnf-plugins/snapper.py 
Problrm with auto generating and auto cleaning snappshots(btrfs). 
SELinux is preventing snapperd from 'rmdir' accesses on the directory 44.

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

If you believe that snapperd should be allowed rmdir access on the 44 directory 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 'snapperd' --raw | audit2allow -M my-snapperd
# semodule -X 300 -i my-snapperd.pp
