Core dump epidemiology: fixing an 18-year-old bug

This article describes OpenAI's investigation and resolution of a longstanding bug in their data infrastructure that had persisted for 18 years, likely related to how core dumps (system memory snapshots created during crashes) were being handled or analyzed. The piece presumably details the diagnostic process, impact analysis, and the fix implemented to address this legacy issue in their systems. This represents a case study in identifying and resolving deeply embedded technical debt within large-scale AI infrastructure.
