I have a server which I'm administrating remotely over SSH, for various reasons, it needs to be restarted. However, when I try to do so,
shutdown goes to uninterruptible sleep almost immediately after sending the wall message.
$ ps aux | grep 'shutdown' root 4754 0.0 0.1 1888 720 ? D 07:26 0:00 shutdown -r 0 w
I have no physical access to the machine at the current time. What should I do? The server is still responding, and I can still log in.
