Game Server Ops Weekly: Linux Memory Tuning & OOM Killer Defense
Technical bulletin for community server administrators: vm.swappiness adjustments, jemalloc memory profiling, and automated log rotation.

Essential Kernel Tuning for Game Nodes
Setting `vm.swappiness=10` ensures Linux prioritizes physical RAM for active game heap structures while safely paging out inactive OS services to high-speed NVMe storage. Combine this with `systemd` memory limits (`MemoryHigh` and `MemoryMax`) to gracefully throttle runaway memory before crashes occur.
