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 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.

In this series of chaos engineering articles, let’s discuss how to simulate CPU consumption to spike up to 100% on a host (or container). CPU consumption will spike up whenever a thread goes on an infinite loop. Here is a sample program from the open-source BuggyApp application, which would cause the CPU to spike up.
