  • The process working on the task has failed without raising an error; or
  • The software being automated (PSS®E, PowerFactory or PSCAD™) has become unresponsive or crashed; or
  • The machine running the gridmo Engine is under extremely heavy CPU load and an intermediate process has become unresponsive; or
  • A combination of the above.

The gridmo Engine has detected this task has potentially failed and will attempt to stop the process and schedule the task to be completed again.

Possible impact:​

  • The current task will be terminated and retried. If the underlying issue is not resolved, the task may repeatedly fail.
