Tmux session stops screen refresh randomly

Question

I am using tmux 1.6-2 on Debian 7.6 (wheezy).

I open a new session and run a long script that gives updates in the form of a progress bar and an activity indicator (rotating bar: / - \ | /).

When I disconnect and reconnect everything, everything is in order. But after some random time, when I reconnect, the contents of the screen get stuck. There is no rotating rod, no progress. I reviewed the following:

• I see from above that the process is still working
• I can successfully enter tmux commands (e.g. new window, disconnect, etc.).
• I can kill the script with Ctrl-C, but the tmux screen does not change
• Ctrl-S and Ctrl-Q (as suggested in other threads) do not help

Any help is greatly appreciated.

Answer 1

I managed to defrost my tmux session by running the choose-client command from the tmux <prefix> : command line <prefix> :

where the default prefix is ​​Cb

I found the solution in the bug report (from Taisuke Yamada).
