In this post, we explored the 'java.lang.OutOfMemoryError: GC overhead limit exceeded', a common challenge for Java developers. We delved into its causes, including increased traffic volume and memory leaks, as well as potential solutions such as fixing memory leaks and increasing heap size. Troubleshooting tips, including capturing and analyzing heap dumps, were also discussed to equip developers in conquering this issue.
jPrime is a conference with talks on Java, various languages on the JVM, mobile, web and best practices. It's run by the Bulgarian Java User Group and backed by the biggest companies in the country. Our architect, Ram Lakshmanan, presented on ‘MEMORY MATTERS: TROUBLESHOOTING 9 TYPES OF OUTOFMEMORYERROR’ Even though at surface level ‘java.lang.OutOfMemoryError’ appears... Continue Reading →
DevNexus is the longest-running and largest Java Ecosystem Conference in the world. Our architect was invited to give a talk on the topic “EFFECTIVELY TROUBLESHOOT 9 TYPES OF OUTOFMEMORY ERROR”. Embark on a journey into the depths of java.lang.OutOfMemoryError as we unravel its complex nature. In this talk, the nine distinct faces of this memory-related challenge... Continue Reading →
In this article, we’ll learn how to improve the performance of the applications that tend to use most of the space due to extensive usage of Strings. There’s no need to store more than one instance of immutable objects in our heap, and String is a good example. Object Allocation Let’s briefly refresh the information... Continue Reading →
Many of us know that allocating more memory than we need may negatively affect the performance of our application. Thus, creating the Lists using a constructor that takes a capacity may make a significant difference. However, this optimization step might not be so straightforward while using Maps. In this article, we’ll learn how to identify... Continue Reading →
Everyone has at least once seen a failing application due to OutOfMemoryError. This error happens because the application cannot allocate the required memory. The specific reason for this problem may differ depending on the severity and heap section affected. However, in any case, we would like to have some actions prepared for this. In this...

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 →
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.

JVM memory has following regions: Fig: JVM memory regions a. Young Generation b. Old Generation c. Metaspace d. Others region Video: To see the visual walk-through of this post, click below: https://youtu.be/yCH6GIxYMGQ When you encounter 'java.lang.OutOfMemoryError: Metaspace' it indicates that the Metaspace region in the JVM memory is getting saturated. Metaspace is the region where... Continue Reading →
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. Video: To see the visual walk-through of this post, click below:... Continue Reading →
