Worked on the DataDog/datadog-agent repository to enhance the stability and correctness of Linux process management by addressing a critical bug in the ProcessKillerLinux component. Focused on backend development using Go, the work involved refining error handling to prevent signals from being sent to processes with invalid CreateTime data, thereby avoiding actions on recycled PIDs. The solution aligned error handling with established psutil patterns, ensuring robust safeguards against procfs lookup failures. Changes were validated through targeted Go tests and code review, resulting in improved reliability and operational safety for Linux process termination logic without introducing new features during the period.
