This bug can be reliably triggered, My concern is that the system then requires a Hard Restart, Power down the server is the only solution for the Server. It will immediately crash when rsync is started. This is new to 18.4 previously we ran this rsync every hour on 16.4 no issues. The model for this is a remote server uses rsync to back or mirror the server.
