When people talk about tmux's ability to survive ssh failure, they usually say: "ssh into your remote box, start a tmux session, run your process, then detach the tmux session. If ssh drops your process will still be alive when you ssh in again".

To clarify: if the ssh connection drops while the tmux session is active (not detached), is the process killed?

No. The TMUX session will survive if your ssh session fails.

Just reconnect to the server and attach to the tmux session with

List tmux sessions: tmux ls
Attach to tmux session: tmux a
Attach to named session: tmux a -t myname
