Diagnosing Excessive Native Memory Usage in a Spring Boot Application Using JVM Native Memory Tracking and System Tools

After migrating a project to the MDP framework based on Spring Boot, the author observed swap overuse and physical memory far exceeding the 4 GB heap; using JVM native memory tracking, gperftools, strace, pmap, and a custom allocator, they traced a native‑memory leak to Spring Boot’s ZipInflaterInputStream during JAR scanning and resolved it by limiting scan paths.

Root Cause Analysis of High Native Memory Usage in a Spring Boot Application

After migrating a project to the MDP framework based on Spring Boot, the system repeatedly reported excessive swap usage; the investigation revealed that native memory allocated by the Spring Boot classloader’s Reflections scanning and InflaterInputStream caused 700 MB–800 MB of off‑heap memory to remain unreleased, which was eventually resolved by limiting the scan path and updating Spring Boot.

Comprehensive Memory Monitoring and Optimization Strategy for the K歌 Android Application

To eliminate the K歌 Android app’s frequent OOM crashes, a four‑stage framework was implemented—development self‑checks, automated testing baselines, gray‑release real‑time monitoring, and production continuous sampling—collecting virtual memory, Java heap, file‑descriptor, thread, and native‑heap metrics, feeding a backend platform that visualizes leaks, guides fixes, and has already resolved over 120 leaks, cutting crashes by more than 25 %.
