Tip: Claude Code Dynamic Workflows Were Sizing Concurrency Off the Host's Core Count Inside CPU-Limited Containers
Claude Code Changelog·medium signal
A 2.1.229 fix corrects dynamic workflows running inside CPU-limited containers using the host machine's core count instead of the container's CPU limit to decide parallelism. If you run agent fan-outs in Docker, Kubernetes, or a CI runner with a CPU quota, prior versions would over-subscribe — spawning concurrency sized for a 16-core host inside a 2-core cgroup. Upgrade if your containerized workflows have been thrashing or timing out under load.
