I've tried multiple times to make this test reliable, and apparently still have not succeeded. Invariably I end up debugging a dump that shows the object is unreachable but not yet finalized. Will just disable it for now.

adamsitnik commented 3 years ago

@stephentoub have you tried to repro https://github.com/dotnet/runtime/issues/57331 ? Should we disable it as well?

ViktorHofer commented 3 years ago

Happened again in https://dev.azure.com/dnceng/public/_build/results?buildId=1301031&view=ms.vss-test-web.build-test-results-tab&runId=38343962&resultId=198394&paneView=dotnet-dnceng.dnceng-build-release-tasks.helix-test-information-tab.

Happened again

It's been disabled. Presumably this run is just from before that happened?

stephentoub commented 3 years ago

have you tried to repro #57331 ? Should we disable it as well?

That's likely a similar cause; I've been unable to make either of these stable, for unknown reasons. I can disable it as well.

ViktorHofer commented 3 years ago

It's been disabled. Presumably this run is just from before that happened?

The test ran on "8/18/2021, 12:57:36 PM" (main).

stephentoub commented 3 years ago

And it was disabled on the 19th.
