AI agents fail mid-execution due to sandbox and memory issues

AI agents running on platforms like Claude or Cursor can unexpectedly fail mid-execution due to issues with their isolation and resource management. These failures, often manifesting as "Isolate was disposed during execution" or "Array buffer allocation failed," stem from problems in the sandbox environment's lifecycle or memory exhaustion when handling large data payloads. Developers need to implement robust solutions for isolation lifecycle management, memory guardrails, and stateful recovery to build reliable agentic workflows. AI
