The article discusses the reasons for different types of OutOfMemoryError, focusing on "GC overhead limit exceeded." It explains how to reproduce and identify the error, considering root causes like memory leaks, overridden finalizers, and slow threads.
Production environments frequently face space shortages due to growing disk usage by files like logs, databases, and output files. Failing to monitor and manage these files can lead to application crashes. The article explores simulating disk storage issues, offering a sample program, and strategies for diagnosing storage saturation, including manual and automated approaches using monitoring tools.
The article discusses the impact of network delays on application performance and presents a method to simulate network lag using BuggyApp as a proxy server. It provides a sample program to introduce delays in server responses and explains manual and automated approaches to diagnose network issues. The article highlights the importance of addressing network performance problems in chaos engineering.
Discover how object pointers can enhance performance in Java programs. Learn about the JVM's object representation in memory and its impact on application performance.
This post helps you troubleshoot JVM deadlock issues in ServiceNow MID server environments. It also explains the causes of deadlocks and demonstrates how to simulate them using a sample Java program. It concludes by stressing the need to monitor and solve deadlocks for better performance.
This article discusses intentionally filling up disk space to test system stability. A script fills disk space by writing data to a file. The Boomi process runs successfully, but the operating system reports a critical disk space shortage, prompting system warnings. It also highlights how the issue was identified and emphasizes the importance of monitoring the system.
This article talks about a common problem with Spring Boot applications: database connection leaks. These leaks happen when connections aren't closed properly, which can slow down the system or even cause it to crash. The article sheds some light on how one can find and fix these leaks by looking at errors and network metrics and also suggests solutions like try-with-resources and connection pools to stop leaks from happening in the first place.
This post explains how to diagnose CPU spike problems that surfaces in the Spring Boot applications.
This post discusses diagnosing and troubleshooting StackOverflowError in Spring Boot applications, which occurs when thread stack size exceeds memory limits due to infinite recursion or excessive stack calls. It demonstrates simulating this error using BuggyAPI and employs the yCrash tool for analysis, providing resolutions such as proper termination in recursive methods and increasing stack memory.
Spring Boot is a framework for creating Java web applications, but it can experience thread leaks, leading to performance issues. A thread leak occurs when threads retain references after execution, causing resource exhaustion. Proper thread management, including termination, use of thread pools, and handling exceptions, is crucial for preventing leaks and ensuring system stability.
