The JVM memory consists of several regions, including the Metaspace, which stores metadata for classes and methods. An 'OutOfMemoryError: Metaspace' indicates that this area is saturated. This article discusses how to simulate this error and addresses its causes, including inadequate Metaspace allocation and memory leaks.
The post discusses troubleshooting a 'java.lang.OutOfMemoryError: Metaspace' issue in a microservice application, which works initially but fails after a few hours. It details identifying memory leaks in the Metaspace region through garbage collection logs and heap dump analysis, ultimately resolving the issue by upgrading a problematic third-party library.
Procedures to diagnose and solve all the 5 types of OutOfMemoryErrors that happen within the JVM heap are same. In this article, let's explore how to diagnose these 5 types of OutOfMemoryErrors.
