Ariel Weisberg commented on CASSANDRA-13090:
--------------------------------------------
Can you be more specific, maybe link to what you are talking about? I looked at
trunk and 3.11 and they look like the patch to me. I also check and they are
based off recent trunk (last commit Jan 27).
I am talking about the dtests where 500 tests fails.
There is this in the logs

> With the current code maybeSleep is called even if we managed to take
> maxItems out of the backlog. In this case we should really avoid sleeping
> because it means that backlog is building up.
> I'll send a patch shortly.
