Process Exhaustion is a new experiment introduced by Gremlin to help organizations test the limits of their systems' process handling capabilities and enhance reliability and efficiency. As systems run an increasing number of concurrent processes, understanding and managing process limits becomes crucial, particularly in modern modular architectures like containers and Kubernetes, where process exhaustion can lead to system instability. The experiment allows users to simulate high process loads by creating new Process IDs (PIDs) until a specified limit is reached, enabling them to observe system responses and identify potential vulnerabilities. Users can choose between absolute or relative allocation strategies and adjust the percentage of PIDs consumed, with recommendations to start small and monitor system behavior using observability tools. Gremlin's platform facilitates the identification and mitigation of availability risks, offering a 30-day free trial for users to explore its capabilities, including Process Exhaustion and other features like AWS Key Management Service support and improved dependency detection.
