Hi everyone, I’ve been doing some learning tests to figure out if temporal is a good fit for us. I’ve been trying to deal with failures for example in case a worker shuts down in the middle of running an activity. If I have a running worker - everything works as expected and the activity retries on…

Could you post the ActivityTaskScheduled event? My guess is that you specified ScheduleToStart timeout and activity fails with it. ScheduleToStart is not retryable. How do you handle the activity failure in your workflow code? By default if an unknown exception is thrown from the workflow function …

[image] maxim: ActivityTaskScheduled [Screenshot 2021-05-19 at 18.48.20] My activity is very simple, it logs something then sleeps for 1 sec (enough time for me to stop the worker in the middle). If activity returns an error the workflow returns the error: err := workflow.ExecuteActivity(…

What does UI show in the summary page about that activity while the workflow is running?

It shows attempt 2 in the scheduled state. So the task is never picked up after the retry.

Well, there is exactly 1 attempt, the second one is only scheduled but never picked up by the worker. These are the last two logs, first row is printed inside the activity, no other logs after that, only the timeout error (even when timeout error is set for a long period) 2021/05/19 20:07:05 INFO …

So my guess is that your first worker doesn’t start correctly if it fails to poll on the task queue.

You can click on the task queue name in the UI to see all the workers connected to the task list.

Thanks for the help! This is what I’m seeing: [Screenshot 2021-05-20 at 9.54.19] If the time hasn’t been updating since the workflow started this means the worker isn’t actually polling the queue?

I’ve tried another flow that’s confirming my worries: 2 workers are running workflow starts one worker stopped in the middle, then restarts second worker picks up and finishes the workflow started at #2 after the first worker is restarted (at #3) we start a new workflow expected: the worker that…

Worker cannot be started after it was stopped. So Start of after the Stop is ignored. Filed an issue for Start to fail in this case.
