@ManickaP:
I did a quick Kusto query and:

"Method": SendMoreThanStreamLimitRequestsConcurrently_LastWaits,
"Result": Fail,
"Arguments": streamLimit: 10,
"count_": 159,
"min_Queued": 2021-07-16T14:42:38.333Z,

So it got broken on 16.7. and fails consistently only for stream limit 10.

Is this failure caused by the problem being tracked here? (linux x64)

Test failures 5/19-7/18 (incl. PRs):

Day	Failures
7/16	19 failures (incl. 1 on official run)
7/17	9 failures (incl. 1 on official run)
7/18	7 failures (incl. 4 on official runs)
7/19 (so far)	4 failures (3 on official runs)

We should disable the test ASAP - @ManickaP are you looking at it?

[ManickaP]

The first two in your table must be mock, which has been disable for a while, you have to filter test type as well.

Yep, sorry, fell for it again. Table is now updated.
