Learn to identify JVM memory leaks in production by monitoring heap usage, analyzing GC logs, using heap dumps and runtime profiling, and applying prevention patterns such as bounded caches, proper resource cleanup, and safe reference handling to avoid OutOfMemoryError crashes.
This guide explains how to enable detailed G1 GC logging in Java, interprets both Minor (YGC) and Full GC log entries, breaks down heap size changes, worker threads, pause times, and points to the GCEasy analysis tool for deeper insight.
This article demonstrates how to trigger and interpret JVM garbage‑collection logs by creating a small Java program, configuring heap parameters, and dissecting both young and full GC log entries to reveal causes, memory changes, and performance implications.
This article explains the G1 (Garbage‑First) garbage collector introduced in JDK7, its region‑based architecture, key differences from CMS, and the complete GC cycle—including Young GC, concurrent phases, mixed GC, and Full GC—while providing real‑world log examples and performance insights for Java developers.
