We would like to extend our thanks to Entwinkler.de JavaMagazin for translating and publishing our article ‘Simulating and troubleshooting deadlocks in Kotlin’ in the German language. It is an honor to have our work published in a print magazine, that too in German language. Here is the translated German version of the article: ‘Simulation und... 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.

In this series of simulating and troubleshooting performance problems in Kotlin, let’s discuss how to simulate StackOverflow errors. StackOverflow error is a runtime error, which is thrown when a thread's stack size exceeds its allocated memory limit. Video: To see the visual walk-through of this post, click below: https://youtu.be/dP-pPahkuLM Sample Program Here is a sample... Continue Reading →
In this series of simulating and troubleshooting performance problems in Kotlin, 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. This error will disrupt the application’s availability. Video: To see the visual walk-through of this post,... Continue Reading →
In this series of simulating and troubleshooting performance problems in Kotlin, let’s discuss how to make threads go into BLOCKED state. A thread will enter into a BLOCKED state when it couldn’t acquire a lock on an object because another thread already holds the lock on the same object and doesn’t release it. Video: To...

In this series of simulating and troubleshooting performance problems in Kotlin 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. Kotlin CPU Spike Program Here is a sample kotlin program, which generates the... Continue Reading →
All multi-threaded applications are prone to deadlock. Modern Kotlin platform is no exception to it. In this post let’s discuss how to simulate a deadlock in Kotlin and how you can troubleshoot it. What is Deadlock? First let's try to understand what 'Deadlock' means. Several technical definitions aren’t clear. ‘Deadlock’ is one among them ;-).... Continue Reading →
