JVM memory has following regions: Fig: JVM memory regions a. Young Generation b. Old Generation c. Metaspace d. Others region
Recently we confronted an interesting ‘java.lang.OutOfMemoryError: Metaspace’ problem in a Microservice application. This Microservice application will run smoothly for initial few hours, later it will start to throw java.lang.OutOfMemoryError: Metaspace. In this post let me share the steps we pursued to troubleshoot this problem.
In this series of simulating and troubleshooting performance problems in Kotlin, let’s discuss how to simulate the ‘java.lang.OutOfMemoryError: Java Heap space’ problem. ‘java.lang.OutOfMemoryError: Java Heap space’ will be thrown by the application, when it generates more objects than the maximum configured heap size.
There are different flavors of OutOfMemoryError. One of the flavours of OutOfMemoryError is ‘Kill Process or sacrifice child’. This post discusses what triggers this ‘Kill Process or sacrifice child’ OutOfMemoryError and potential solutions to diagnose this problem.
In the series of chaos engineering articles, we have been learning to simulate various performance problems. In this post, let’s discuss how to simulate ‘java.lang.OutOfMemoryError: Java Heap space’ problem. This ‘java.lang.OutOfMemoryError: Java Heap space’ will be thrown by the application when the application generates more objects than the allocated heap size.
It’s great to explore the world of Virtual Threads, a powerful feature in Java that promises to revolutionize multi-threaded applications. In this article, we’ll delve into how Virtual Threads can enhance your application’s performance and scalability, all while keeping thread management overhead very minimal. Let’s embark on this journey to harness the full potential of… Continue Reading →
Learn how to troubleshoot OutOfMemoryError using the Eclipse MAT tool. You will learn best practices, cool tips & tricks to debug memory problems effectively. Watch this video to know more!
In this post let’s discuss an interesting memory problem we confronted in the production environment and how we went about solving it. This application would take traffic for a few hours after that it would become unresponsive. It wasn’t clear what was causing the unresponsiveness in the application.
