GENREL03-BP02 Implement timeout mechanisms on agentic workflows

Implement controls to detect and terminate long-running unexpected workflows.

Desired outcome: When implemented, this best practice improves the reliability of your generative AI workload by freeing resources that might have been consumed by unexpected long-running execution loops.

Benefits of establishing this best practice: Automatically recover from failure - Implementing agent timeouts helps to reduce the likelihood of blocking failures on agentic workflows and executions.

Level of risk exposed if this best practice is not established: High

Implementation guidance

Agentic workflows act on behalf of a user by making calls to external systems. External systems may themselves perform several time-consuming tasks which the agent is not aware of, resulting in idle agents that could run for an extended period. To maintain a reliable agentic system, implement controls to manage agentic timeout.

One approach to controlling agentic runtime or lifecycle is to implement runtime timeouts on the external infrastructure. For example, if an agent makes a call to a function through an Action Group, consider applying a timeout to the corresponding function. The timeout should be set to include the maximum allowable time needed to complete a process, accounting for additional latency for edge cases such as cold starts. You may consider rounding this value up to avoid unnecessary early terminations.

Alternatively, consider connecting agentic workflows to an event system, developing an asynchronous process management architecture. Introducing an asynchronous event system gives users the most flexibility and visibility into agent process lifecycle or flow. By requiring the compute underpinning an Action Group to publish events, workload owners maintain insight into where an agent may encounter stalled flow or process. Consider using events to publish agent updates and act appropriately to stop long-running invocations.

Error handling at the agent layer should be transparent to users. When errors occur, communicate clear details about the issue while maintaining system security by avoiding exposure of sensitive internal information. The response should outline specific next steps so that users can complete their tasks independently if the agent remains unavailable. This approach promotes operational resilience while maintaining security best practices, as users receive actionable guidance without compromising system integrity.

Implementation steps

  1. Create an agent workflow configuration:

    • Define maximum runtime thresholds

    • Set up timeout controls at function and workflow levels

    • Configure event publishing for process monitoring

  2. Implement timeout mechanisms:

    • Add timeouts at the agent layer to terminate sessions waiting for user input

    • Configure timeouts on external compute resources

    • Set up dead letter queues for timed-out processes

  3. Establish monitoring and alerting:

    • Track agent execution times

    • Monitor timeout frequency

    • Alert on repeated timeouts

  4. Define recovery procedures:

    • Create graceful termination processes

    • Implement cleanup routines for timed-out sessions

    • Set up automated retry mechanisms where appropriate
