JVM Memory Leak Detection Guide

There are several ways to check for JVM memory overflow.

1. Check the JVM log files: You can identify potential memory overflow issues by reviewing the JVM log files. Typically, if a memory overflow occurs, there will be corresponding error messages in the log files.
2. Utilize Java monitoring tools such as VisualVM and JConsole to monitor the memory usage of the JVM. These tools allow you to view the memory situation of the JVM in real-time, including the usage of heap and non-heap memory, aiding in the prompt detection of memory overflow issues.
3. Analyze heap dump files: You can generate a heap dump file when a memory overflow occurs, and then use analysis tools like MAT (Memory Analyzer Tool) to examine which objects are using too much memory.
4. By using JVM parameters, you can set parameters such as -Xmx and -XX:HeapDumpOnOutOfMemoryError when starting the JVM to adjust the heap memory size and generate a heap dump file in case of a memory overflow, making it easier to troubleshoot issues.

By using the above method, JVM memory overflow issues can be promptly identified and addressed accordingly.
