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 StackOverflow error. StackOverflow error is a runtime error. In this post let’s discuss how to simulate StackOverflowError, diagnose it and solve the 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 thread leaks. ‘java.lang.OutOfMemoryError: unable to create new native thread’ will be thrown when more threads are created than the memory capacity of the device. When this error is thrown, it will disrupt the application’s availability.

In this post, we are going to discuss how to find your Java application process Id quickly. For certain monitoring tools like yCrash, you need to pass your application process Id as input. If you want to look for a more detailed post with several different options to find your application’s process Id, you can refer to this blog post.

What happens behind the scene when a java program is executed? In which regions objects are created? When objects become eligible for garbage collection? Where are threads stored? What is the difference between Stack and Heap? Watch this video to know more.

Java applications tend to contain hundreds (sometimes thousands) of threads. The majority of these threads are in WAITING, TIMED_WAITING (i.e., dormant) state, while only a small portion of the threads are actively executing lines of code. So, we were curious to know whether dormant threads consume less memory than active threads.
To figure out an answer to this question, we conducted a small study. Our findings were interesting, thus sharing with you.

When you are running your Java application in physical servers, you would have been using ‘-Xmx’ JVM argument to specify the Java heap size. If you are porting your application to Containers, you might be wondering how to configure Java heap size in the container’s world? Are there any best practices? In this article, we will discuss the possible JVM arguments that can be used to specify the Java heap size and the best option to choose.
