After uninstalling Citadel groupware from my headless Debian system located on a remote VPS, obviously something went wrong during removal:
Everytime I try to connect by ssh to that system, the console is littered by continuous broadcast messages, issued by a Citadel process, that had not been uninstalled properly.
Now it is not possible to stop the messages by simply pressing CTRL+C or CTRL+Z. So the messages keep coming... and I have no access to the console, so it is not possible to issue any command.
Rebooting did not solve the problem.
Does anyone of you have a suggestion to regain access to the console?
