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

OpenAI Blog · 2 weeks ago

OpenAI engineers analyzed large-scale core dumps to identify the root causes of rare infrastructure crashes in their systems. They discovered an 18-year-old software bug alongside a hardware fault, using the crash data to trace issues that had persisted undetected for nearly two decades. The findings enabled them to fix both the legacy code defect and address the hardware problem, improving system reliability.
