Some tests affected after r267763


Regarding this last one, I could not reproduce it locally and the bots aren't generating the crash dump like the others.

Snippet of the trace (full one attached):

I have to fix the DNS resolver.
Comment 2 Lauro Moura 2020-10-02 10:44:57 PDT
For completeness, the test below is also flaky crashing with the same trace (had to check locally, the bot was not generating trace for it).
