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.
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.
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!
JVM has provided helpful arguments to deal with OutOfMemoryError. In this article we would like to highlight those JVM arguments. It might come handy for you when you are troubleshooting OutOfMemoryError. Those JVM arguments are:
Troubleshooting OutOfMemoryError or any memory related problem is done in manually even in 2019. Troubleshooting and identifying the root cause of OutOfMemoryError can even be automated, by following below mentioned 3 steps:
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.
