Error Code: Engine Watchdog Timeout
Engine Watchdog Timeout occurs when the Nre:Engine thread becomes unresponsive. This happens when inappropriate actions are run on the Engine Thread that block its execution. Available policies are: Log, Terminate, or Reboot (Controllers only). Solution: Avoid running blocking operations on the Engine Thread. Use proper threading for long-running operations. Review control point onExecute() methods to ensure they dont perform blocking operations. Check for infinite loops or heavy computations in control logic.
