Multi-Agent Session State Loss on Restart
warningDefault in-memory execution of CrewAI crews means that server restarts or process crashes during long-running workflows result in complete state loss, forcing full restart of 20+ step tasks and wasting resources.
Detect crew session interruptions by monitoring for incomplete sessions (started but never completed), tracking session duration vs. expected duration, and identifying server restarts during active crew execution. Alert when sessions fail to complete after process restarts.
Implement persistent state management for crew workflows. Serialize agent progress and intermediate outputs to durable storage (database or file system). Enable workflow pause/resume capabilities. Design crews to checkpoint state after critical task completions. Monitor checkpoint frequency and age to ensure state is fresh enough for meaningful recovery.
