CP-RC-F43BC22B
An unbounded image metadata cache introduced a memory leak in checkout-api v2.4.1.
The checkout API outage was caused by the unbounded image-metadata cache leak in checkout-api v2.4.1, resulting in monotonic heap growth, stop-the-world garbage collection pauses, and pod OOM kills.
Measured in this experiment. No statistical significance is claimed.
Reactive concurrent policy reached quiescence
Finished analysis
The critique supports the revised hypothesis pointing to RC_MEMORY_CACHE_LEAK_V241, confirming that alternative root causes like database saturation, payment provider errors, and traffic spikes are disproven by temporal and metric evidence.

Revised hypothesis confirming the checkout API outage is caused by the unbounded memory cache leak in v2.4.1, backed by new evidence and claims showing monotonic heap growth, OOM kills, and recovery upon disabling the image metadata path or rolling back.

Finished analysis
Evidence identifies the unbounded memory cache leak in v2.4.1 as the primary root cause, supported by monotonic heap growth, canary memory accumulation, OOM restarts, and immediate recovery when the image metadata path was disabled or rolled back.

Finished analysis
Critique of the current hypothesis, highlighting that payment provider errors, traffic spikes, database saturation, and CPU/GC pressure are contradicted by the timeline and metrics, as heap pressure and OOM-kills on v2.4.1 follow different root causes.

Finished analysis
The checkout API outage was primarily caused by the unbounded image-metadata cache introduced in checkout-api v2.4.1, leading to heap pressure, severe GC pauses, and OOM-killed pods.
