[Bug]: Massive memory leak (~26GB) in Docker container triggers Host OS OOM Killer

[Ollec]

The open-terminal Docker container experienced a catastrophic memory leak, consuming all available host RAM (approximately 25.7 GB). This completely locked up the host operating system, preventing SSH and WebGUI access, until the Linux kernel's OOM (Out of Memory) killer eventually intervened and terminated the container.

Environment:

Host OS: Unraid 7.2.3 (Linux kernel 6.12.54)

Deployment: Docker container

Version:
I don't know the best way to check the version

docker inspect -f '{{ index .Config.Labels "org.opencontainers.image.version" }}' open-terminal
main

docker inspect -f '{{ .Image }}' open-terminal
sha256:1e4e62436afc355527086bcaadf4b9e3547562be6682adec6b187c99a74f5eab

Steps to Reproduce:

I barely tested it earlier today. I asked it to run "print("Hello, World!")", and it succeeded. However, I had not touched it since then.

Expected Behavior:

The container should maintain a stable memory footprint and not consume unbound host resources.

Logs / Evidence:

Below are the host kernel logs showing open-terminal (PID 3809247) consuming ~25.7GB of RAM (anon-rss:25713700kB) before being terminated by the kernel:

Mar 11 13:21:27 Groker kernel: oom_reaper: reaped process 3809247 (open-terminal),

Sorry, I don't know what more I can do to figure out WHY it used up all the memory, I ended up restarting the server.

Should be addressed with the latest, keep us posted!

Sounds good I updated and set a ram limit so I will let you know if I see anything else weird
