No worries—thanks for following up on it!

That’s very interesting, about the concurrent requests, because the “normal” report does around 80% more requests per day than the “leaky” one — a few hundred thousand vs a couple of million.

Does this CLOSE_WAIT sockets issue have a bug being tracked or anything like that? I’ve probably overlooked the discussion on the list.
