Diagnosing Java Native Memory Leaks (JNI, Direct Buffers, and OS Tools)
Does your application’s performance gradually degrade over time? Or does it run perfectly for weeks, then suddenly crash with an OutOfMemoryError? Maybe your container application mysteriously disappears from time to time, thanks to the dreaded OOM killer. Chances are, you have a memory leak. Plenty of diagnostic guides deal with finding heap-related memory leaks, but... Continue Reading →
ClassLoader Leaks in Hot-Reload Environments
Hot redeployment in Java saves time by allowing software updates without JVM restarts, crucial for web server uptime. However, classloader leaks can complicate this, causing memory issues due to lingering references. Identifying and addressing these leaks includes using logs, heap dumps, and strategies like properly terminating threads and cleaning resources.
Sizing Your Heap Correctly: Understanding -Xms and -Xmx
Java applications benefit from properly adjusted heap sizes, as default settings may lead to performance issues or excess costs, especially in cloud environments. Monitoring garbage collection metrics is crucial for optimal heap management. Using command line options to configure heap size can enhance efficiency and reduce operational expenses significantly.
