Closed dignifiedquire closed 1 year ago

dignifiedquire commented 1 year ago

Encountered this recently, unclear what exactly is going wrong, but sth doesn't seem to always work out.

I could not find the root cause as well. Anyway, thanks for the report and pull request.

Managed to get at least a report, this was in a long running process, and the mac was asleep, and when I woke it up I saw these messages.
