[Bug] Terminal Bash Process Not Correctly Closed

[MrMYHuang]

I use this script to start my Open WebUI + OpenTerminal:

docker run -d -p 3000:8080 -e OLLAMA_BASE_URL=http://host.docker.internal:11434 -v open-webui:/app/backend/data --name open-webui ghcr.io/open-webui/open-webui:main

docker run -d --name open-terminal -p 3001:8000 -v open-terminal:/home -e OPEN_TERMINAL_MULTI_USER=true -e OPEN_TERMINAL_API_KEY=aaaa ghcr.io/open-webui/open-terminal

I can open the terminal by clicking the "Terminal" title bar as shown in the screenshot:

I can click the title bar again to "close" the terminal. However, I find a bug: the (bash) terminal is not really closed! If I open a new terminal, and run ps ux, I can see the previous bash still there.

If repeat the opening/closing terminal upto 15 times or more, you might see the following error (or the terminal just hangs):

Please fix this bug.

I have an imperfect workaround - use TMOUT to auto logout bash:

TMOUT=300
readonly TMOUT
export TMOUT

The imperfection is: if you want to set a system wide TMOUT, e.g., /etc/profile, the system wide setting file will be discarded after recreating the open-terminal container (e.g. after updating to a new open-terminal image).

Could provide a fix to open-terminal so that this workaround setting is kept after recreating the container?
