There is nothing to prevent a user from trying to save a new configuration file while the logger is running. This either results in Domino freezing or quitting.

At least once, I was forced to manually power off my computer to stop the problem, as the computer wouldn't restart or shut off because Domino was still running, but also wouldn't force quit Domino.
