Heorhi,

I could not reproduce this behavior with zsh or bash.

In case I misunderstood, the steps I took to reproduce were,

[On ssh server machine running 3.12]
1.  Add 'set-option -g default-shell /usr/bin/zsh' to /etc/tmux.conf
2a. In terminal window, 'sudo tmux'
      - also tried -
2b. At root login on tty2, 'tmux'

Successfully starts tmux session. Then,

[On ssh client machine]
1. 'ssh user@server'
2. 'sudo tmux attach'
3. Switch to 2nd terminal window,
4. ps -ef | grep ssh
5. kill $pid_from_step4

This *did not* leave the 'tmux attach' process alive.

Is zsh your login shell as well? Maybe that's the required
component to reproduce the behavior you've observed.

Peter Hurley
