Why Redis Exits on ARM64: Fix the THP COW Bug and Prevent Data Loss

Redis on ARM64 platforms may abort startup with a warning about a kernel COW bug when Transparent Huge Pages are enabled, risking RDB corruption; this guide explains the underlying issue, when it’s safe to ignore the warning, and provides two solutions—disabling THP or configuring ignore‑warnings—to ensure safe operation.
