Your question is Debug Silent Memory Leak. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain how you would trace and debug a silent memory leak in a microservices architecture running under heavy production loads.
Describe a practical investigation plan that protects availability while narrowing the leak to a service, dependency, or infrastructure layer. Cover instrumentation, heap and allocation analysis, cross-service correlation, mitigation, rollout safety, and the evidence required before declaring the issue resolved.
