    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.

    Regards,
    Peter Hurley
