[Hsin-Yi Tsai (she/her) [:hsinyi]]

The intermittent failure rate rose up. Would you be able to take a look, Michael?

Comment 12

[Nika Layzell [:nika] (ni? for response)]

From the occurrences appearing in the orangefactor link, it looks like this timeout is only occurring on 32-bit linux builds. In addition, it appears as though the problem is just that process creation, especially spamming it like is done in this test, is really slow. In the test which is timing out we create at least 14 new content processes.

I'm inclined to request a longer timeout (Currently it's only requestLongerTimeout(2), so I could probably bump it up to 4), or disable the expensive large allocation force-enable tests on linux32 (as we never actually respect the Large-Allocation header in 32-bit builds. The disadvantage of disabling here would be that if we decide in the future we want to respect the header on all 32-bit platforms, we won't have testing.

Trying a longer timeout first sounds good.
