Stop a single leaking service from crashing your entire Linux host. Learn how to use cgroup v2 and systemd to implement hard memory and CPU limits that isolate failures.
Learn how to use cgroup v2 and systemd to implement hard and soft resource limits for Linux services, preventing system-wide crashes caused by memory leaks or CPU spikes.
Goal I run a low-traffic Go HTTP service in a cgroup v2 container (Kubernetes, memory limit 256Mi) and want to shrink its idle memory footprint to cut costs. Go 1.19+ offers GOMEMLIMIT as a soft memory limit that makes the GC more aggressive, but the runtime does not automatically read cgroup v2 memory.max to populate it. Constraints and uncertainty Because
