I dearly wish overcommit could be disabled per-cgroup, but AFAIK this is not possible.
malloc failing seems like a much simpler indication of memory pressure than the alternatives like PSI.
- zozbot234 5y agoAIUI, you can always use plain old ulimit to restrict virtual memory usage per-process, which has the same outcome as disabling overcommit.
- rrss 5y agoyeah, for a single process. but I’m mostly interested in doing this for a process tree (like a browser), and I don’t think this would work well in that case, since the limit would apply to each process individually. this would work if there was a cgroup virtual address space controller, but I think those have been proposed but never merged.
