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.

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.

At the time (March 2020) of writing this article there are 600+ arguments that you can pass to JVM just around Garbage collection and memory. If you include other aspects, total JVM arguments count will easily cross 1000+. 😊. It’s way too many arguments for anyone to digest and comprehend. In this article, we are highlighting seven important JVM arguments that you may find it useful.

ConFoo.CA Developer Conference is one of the biggest conferences for web developers, that took place in Canada. This Conference had 155 presentations by popular international speakers focused on pragmatic solutions for developers, enthusiastic attendees and delightful atmosphere!
Eclipse MAT, Heaphero are all popular java tools to analyze large size heap dumps. Recently we ran in to an interesting problem when trying to analyze a heap dump file in Eclipse MAT. Tool was crashing because of missing font 😊. We thought we will share with you what we found out.
