An unbounded image metadata cache introduced a memory leak in checkout-api v2.4.1.
The checkout API outage was caused by an unbounded image-metadata cache introduced in checkout-api v2.4.1, resulting in monotonic heap growth, increased garbage collection pressure, and pod OOM kills.
Measured in this experiment. No statistical significance is claimed.

Reviewing the hypothesis that RC_MEMORY_CACHE_LEAK_V241 caused the outage. The evidence provided confirms OOM-kills and memory growth linked to v2.4.1 pods, contradicting alternative external failure hypotheses.

Attacking alternative root causes. Database pool saturation, payment provider errors, and traffic spikes are disproven by timestamps and stable metrics showing they were downstream effects or unrelated.

Finished analysis
The checkout API outage was caused by an unbounded memory leak in the v2.4.1 image-metadata cache, leading to severe GC pressure, OOM kills, and pod restarts.
