3,200% CPU Utilization: Unprotected Concurrent Modification Data Corruption in Multithreaded Java Application
In this real-life case study, Joseph Mate shares his experience with a severe performance issue caused by unprotected concurrent modification data corruption within a multithreaded Java application. Despite multiple layers of error prevention measures failing to detect the problem initially, adopting a layered approach ultimately led to its identification and resolution. The article emphasizes the importance of code reviews, static analysis tools like SpotBugs (formerly FindBugs), JLint, Chord, thorough testing with multithreaded scenarios in mind, as well as implementing proper synchronization mechanisms such as locking or using thread-safe data structures to prevent race conditions.
