This article starts from the three core goals of GC tuning and combines them with a real-world off-heap memory leak investigation case to provide a systematic approach to performance tuning and practical troubleshooting methods.</p> <p>In complex distributed systems, memory issues are often the hardest to diagnose. Off-heap memory leaks in particular, occurring outside the JVM heap, are difficult to detect with conventional GC monitoring tools and can easily cause systems to crash suddenly in production environments. This article shares a complete off-heap memory leak investigation process, hoping to provide valuable reference for readers.</p>
