Hi,
I think the directory Workhours_2017 is deleted on master and on
slave it's failing to delete because there might be stale linkto files
at the back end. These issues are fixed in DHT with latest versions.
Upgrading to latest version would solve these issues.
To workaround the issue, you might need to cleanup the problematic
directory on slave from the backend.
Thanks and Regards,
Kotresh H R
