Hi,

I run Wolf inside an LXC container. When an application crashes due to what I've been able to discern is memory shortage, the whole LXC container becomes nearly unresponsive, CPU usage bottoming out. The Wolf Docker container continues to run, though you can't connect to it or anything, and if I'm lucky, I can get a command through to (slowly) stop it, which resolves the situation.

I don't know where in the stack this would or could be alleviated, if at all. Docker log is not really showing anything at the time of the crash.

Originally created by @Lombra on GitHub (Jun 19, 2025). Original GitHub issue: https://github.com/games-on-whales/wolf/issues/214 Hi, I run Wolf inside an LXC container. When an application crashes due to what I've been able to discern is memory shortage, the whole LXC container becomes nearly unresponsive, CPU usage bottoming out. The Wolf Docker container continues to run, though you can't connect to it or anything, and if I'm lucky, I can get a command through to (slowly) stop it, which resolves the situation. I don't know where in the stack this would or could be alleviated, if at all. Docker log is not really showing anything at the time of the crash. ```yaml services: wolf: image: ghcr.io/games-on-whales/wolf:dev-zero-copy environment: HOST_APPS_STATE_FOLDER: /etc/wolf WOLF_LOG_LEVEL: debug volumes: - /etc/wolf:/etc/wolf - /tmp/sockets:/tmp/sockets:rw - /var/run/docker.sock:/var/run/docker.sock:rw - /dev:/dev/:rw - /mnt/udev:/run/udev:rw device_cgroup_rules: - 'c 13:* rmw' devices: - /dev/dri - /dev/uinput - /dev/uhid network_mode: host restart: unless-stopped ``` ``` Starting default_wolf_1 ... done Attaching to default_wolf_1 wolf_1 | [2025-06-13 19:18:53] wolf_1 | [2025-06-13 19:18:53] [ /etc/cont-init.d/10-setup_user.sh: executing... ] wolf_1 | [2025-06-13 19:18:53] **** Configure default user **** wolf_1 | [2025-06-13 19:18:53] Container running as root.

When the host OS runs out of memory there are so many things that start failing in a "last resort" attempt at claiming some memory.

I'm not sure there's anything specifically that we can do in Wolf, but I'm open to suggestions..

Is there any reliable profiling tools available? If so we could hook that in to the Wolf containers and at least be able to get a heat map of what is causing this recursive "last ditch attempt of survival but never outright crashing" behaviour.

Understanding the "how it happens" and in which order things start to choke could lead to a possible solution.

But as with most software, outside of writing an entire scheduler around wolf which actively manages all possible processes, when hardware runs out it runs out.

I've not used these Docker features before, but I learnt that you can set some restrictions on system resources on containers. Wolf applications are launched as separate containers as I discovered, so I can't set any restrictions on those. (?) I tried setting 1 GB reserved memory for the main container, but that didn't seem to help. It wouldn't be a particularly smart solution, but if I could hardcode a memory limit for the application containers, maybe that could work?

Hey @Lombra

In the config.toml you can apply launch options for the app in the variable

base_create_json = """
{
  "HostConfig": {
    "IpcMode": "host",
    "CapAdd": ["SYS_ADMIN", "SYS_NICE"],
    "Privileged": false
  }
}
\
"""

There are options for setting memory and cpu limits here:

@Lombra commented on GitHub (Jun 22, 2025):

Thank you!

I set a memory limit on the Steam container, which prevents it from taking the rest of the system down with it, so that's a big improvement, at least. The Moonlight stream remains intact, but the application soft locks. In the case of Steam, it seems like steamwebhelper locks up. Terminating it via the shell salvages the session.

A couple of similar options to explore:

<!-- gh-comment-id:2994452376 --> @Lombra commented on GitHub (Jun 22, 2025): Thank you! I set a memory limit on the Steam container, which prevents it from taking the rest of the system down with it, so that's a big improvement, at least. The Moonlight stream remains intact, but the application soft locks. In the case of Steam, it seems like `steamwebhelper` locks up. Terminating it via the shell salvages the session.

@Lombra commented on GitHub (Jul 6, 2025):

I've settled for a cgroup for now, managed by systemd.

Create a slice file, defining the resource limits:
/etc/systemd/system/docker.slice

[Unit]
Description=Slice that limits docker resources
Before=slices.target

[Slice]
MemoryAccounting=true
MemoryMax=19G

Documentation recommends using MemoryHigh rather than MemoryMax, as a soft limit, but that just seems to cause containers to freeze rather than crash.
Configure Docker to use the cgroup.
/etc/docker/daemon.json

{
	"cgroup-parent": "docker.slice"
}

Now, all Docker containers has a shared memory quota of 19 GB. (as far as I understand) This way I don't need to configure containers individually.

It is also possible to set a percentage value, but that didn't seem as useful as I first imagined.
