FastFlood: The Story of a Massive Memory Leak in FastBoot Land
summary
A production FastBoot app leaks roughly 90% of memory across requests and reproduces locally only when built like production. Investigation uses Chrome DevTools Heap profile and timeline plus node inspect and ApacheBench with concurrency 1, applying a three-snapshot technique to shrink candidates. The leak traces to Ember Data and a custom adapter where a computed headers property holds token references; replacing it with a plain getter removes the leak and restores normal memory behavior.
