- MemoryMax=1536M, MemoryHigh=1200M (1.5GB hard limit, 1.2GB soft) - CPUQuota=200% (max 2 cores) - StartLimitInterval=120s, StartLimitBurst=5 (rate-limit restarts) - Add --max-old-space-size=1024 to Node heap - Add --heap-snapshots --snapshot-interval 30 for leak debugging Prevents runaway memory/CPU from taking down the host. Watchdog already implemented in bd-ch6.6 (Type=notify, WatchdogSec=30). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> Bead-Id: bd-ch6.8
