Workerman requires pcntl and posix on Linux; without them the relay printed "Please install pcntl extension" and exited immediately, Docker kept restarting it, and nginx's DNS lookups for dmtools-puzzle-relay intermittently failed whenever it happened to be down mid-restart - the "could not be resolved" errors were a symptom of this crash loop, not a separate networking problem. Local dev never hit this because Workerman's Windows code path doesn't need either extension. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
