Draft outline details
Step by step
- Run a 20-minute load test of checkout: green.
- Start the soak at moderate load and open heap and GC dashboards.
- Planned mistake: judge success from the first 20 minutes; at hour one old-generation memory keeps climbing and GC pauses grow.
- Take a heap dump or profile; find the growing cache or unclosed resource.
- Fix it, rerun the soak, and show flat memory.
- Write the finding with graphs and the evidence chain.
