Back to newsletter 223 contents

This month is a special newsletter on memory leaks, extending my Devoxx masterclass on Quickly Analysing A Heap Memory Leak (and the tips from that are in this month's tips page if you want the very short version.

Solving memory leaks has a known step-by-step procedure. It might take time, but you should be able to do it. The steps are straightforward:

  1. Do I have a leak (and does it needs fixing) ?
  2. What is leaking (instances of which classes) ?
  3. What is keeping the objects alive (what instances in the app) ?
  4. Where is it leaking from (the code where the objects are created and/or assigned) ?

The complexity comes not from needing to know what to do, but instead comes from the large variety of ways you can have a leak (heap, native, metaspace, classloaders, statics, sessions, threadlocals, pools, ...), and from the many different tools you need to use to answer the full set of questions completely. The links in this newsletter give you everything you need, and you might notice the new Heap dump analysers menu option in the menu bar above. Now on to those links, tips, tools, news, articles, and talks that will help you solve your memory leaks. And of course the tips from this month's articles and talks, as ever are extracted into this month's tips page.
