An unbounded image metadata cache introduced a memory leak in checkout-api v2.4.1.
The primary root cause of the checkout API outage is the unbounded memory cache leak introduced in checkout-api v2.4.1, leading to heap pressure, GC pauses, OOM-kills, and eventual service degradation.
Measured in this experiment. No statistical significance is claimed.

The primary root cause of the checkout API outage is the unbounded memory cache leak introduced in checkout-api v2.4.1, leading to heap pressure, GC pauses, OOM-kills, and eventual service degradation.
Started analysis
Finished analysis
The hypothesis is well-supported by evidence showing heap growth leading to OOM-kills and increasing GC pause times, while alternative root causes like database saturation, payment provider outages, and traffic spikes are contradicted or shown to be downstream effects.

The checkout API outage was primarily caused by the unbounded memory cache leak introduced in checkout-api v2.4.1.
Started analysis
Finished analysis
Evidence identifies the unbounded memory cache leak in v2.4.1 as the primary root cause, supported by monotonic heap growth, canary results, and immediate recovery when the image metadata cache path was disabled and rolled back.
