I Found a Significant Revenue Leak Hidden Inside Out-of-Memory Errors

A routine investigation into why a public-facing API was missing its 99.9% availability target revealed that out-of-memory errors in the application runtime were silently killing end-user requests — leaving no trace in error logs. By tracing the root cause to a bloated data model and a multiplicative explosion of API calls in a post processing framework, I fixed the issue and brought the service availability above the target. The unexpected bonus: eliminating those silent failures delivered a significant revenue increase and measurable improvements in the UI page load times.
