What is a memory leak?
If memory grows unbounded and never reaches a steady state then there is probably a leak. The key here is that memory grows without ever reaching a steady state, and eventually causes problems through explicit crashes or by impacting system performance.
Memory leaks can happen for any number of reasons. There can be logical leaks where data-structures grow unbounded, leaks from complexities of poor object reference handling, or just for any number of other reasons. Regardless of the source, many memory leaks elicit a visually noticeable pattern: the “sawtooth”.
The goal of our analysis is to progressively narrow scope of the problem by whittling away possibilities until we have enough information to form and propose a hypothesis.
Just to reiterate we’ll try to:
- Ask a question
- Form a Hypothesis
- Analyze the hypothesis
- Repeat until the root cause is found
