I recognise that I will probably have no choice but to force reset the server in question, but I wonder if anyone can offer any insight as to why this is happening.
I can ssh into my Virtual Private Server just fine.

I can even resume my tmux session!
$ tmux a -d
I notice my weechat client seems to have frozen. Not to worry, I'll kill it from another tmux window. Time to find that process ID.
$ ps aux ■
Weird, it's printing nothing. Perhaps the problem is in tmux. I'll detach and try some other commands.
$ ls ■
Nothing at all? What's going on? Well it printed some things when I logged in, so some things must work...
$ uname Linux
