NeedsInvestigation
Someone must examine and confirm this is a valid issue and not a duplicate of an existing one.
Testing
An issue that has been verified to require only test changes, not just a test failure.
Milestone
There is a strange effect visible in this log on the
darwin-arm-mg912baios
builder.The tests are running along fine for a while, and when they get to the (presumably CPU-intensive)
hash/*
tests they suddenly dropm from ~150s per test to ~19m per test.The first couple of
image
tests are similarly slow, but then the builder seems to recover:I wonder if that implies some sort of resource contention (perhaps a thermal limit?) between the tests — should we reduce the parallelism of that builder to decrease the likelihood of spurious timeouts?
