[WORKFLOW SDK BUG] Unrealistic number of warnings being generated by the durabletask-worker

[alkofahi-kantar]

Expected Behavior

I have a workflow with external events, I have a timer configured for a timeout as seen below. I could not confirm if this is the root of all of the logs that I got, but my expected behavior is that if an unexpected timer is fired to not spam my logs.

wf_completion_event = ctx.wait_for_external_event(event_name)
timeout_event = ctx.create_timer(timedelta(hours=24))
winner = yield when_any([wf_completion_event, timeout_event])

Actual Behavior

I do not have the steps to reproduce this issue, but the couple of times it happened were after an activity had retried. My logs are spammed with +1k lines of warnings (snippet below) from a single request. Not sure if this is due to the timer I configured or something else.
