zmd-updater hang on FTP timeout

Hi, This evening there were some security updates available in zmd-updater. I pressed go, and after a certain amount of disc and network traffic, and some CPU use, everything has gone quiet, and the update is not complete. The last few lines of /var/log/messages/zmd-backend.log are attached (to avoid wrapping them). At the moment, the zmd-updater front end is completely greyed out, with the title-bar "Updating Software - 0%", and nothing is happening (network/cpu/disc). What do I do next? How can I get it cleanly restarted to try again? It looks as if there is no handling of an FTP timeout in zmd-updater. Is that true? <jaw drops> -- Bill Gallafent.
