Solving Java Memory Leaks
Live Workshop, June 6, 2019 12am EDT
Java's memory management is amazing. It allows developers to allocate seemingly infinite amounts of memory. That is, until you hit the dreaded OutOfMemoryError. Even if you're not experiencing an OutOfMemoryError, it might be that your application is consuming too much memory. And, if I'm not seeing an OutOfMemoryError, how can I tell if my application is consuming too much memory? How does this happen and more to the point, how can it be fixed.
This workshop will give you the answers to these questions. It covers several common scenarios that can cause the JVM to fail with an OutOfMemoryError. We’ll explore tooling and methods that can be used to diagnose the cause of an OutOfMemoryError. Finally, this is a workshop and that means you’ll go toe to toe with several applications that are failing with an OutOfMemoryError. Topics that will be covered include;
- Overview of Java heap
- Allocations in Java heap
- GC basics with Mark and Sweep
- Normal life cycle of a Java object
- Common causes of OutOfMemoryError
- Anatomy of a memory leak
- Tools for detecting memory leaks and other memory ineffeciencies
