It's important to be able to figure out what's going on when things go wrong in your Node.js production application. Tools are needed to investigate memory leaks, crashes and other "interesting" events in production. The post-mortem community working group (https://github.com/nodejs/post-mortem) is working on these problems. Come and learn about the key issues being worked, and the progress of the working group so far as illustrated through examples and code.
