You've most likely a dead disk drive. My guess is that you are using btrfs or zfs. Any command that attempt to interact with the file system kernel module will zombie, making the shell useless. If you still have screen on the remote machine, I would create a new shell and read the syslogs and dmesg to determine which disk failed.<div>

We have a server in a remote data center that is having problem - I can ping it from another machine behind the firewall, but no ssh - hangs at negotiating the protocol.<br>
<br>
I *do* have an old bash session open from another machine in screen - the first two new-lines produced a prompt, however when I tried to do a 'df -h' I get no reply - just newlines. Tried <ctl>C (echos), .. <ctl>D (just a newline), .. characters & commands (just echo).<br>
<br>
Is anyone aware of a way to exploit this 'open' connection? Tried launching shell or bash, but nothing except the character echo.<br>
<br>
Thanks!<br>
