is this consistent repro? this looks more like something wrong with machine rather than JSON

[jakobbotsch]

is this consistent repro? this looks more like something wrong with machine rather than JSON

We saw the same failure in libraries-jitstress on two different machines:

https://dev.azure.com/dnceng/public/_build/results?buildId=1871584&view=ms.vss-test-web.build-test-results-tab&runId=49033894&resultId=165363&paneView=dotnet-dnceng.dnceng-anon-build-release-tasks.helix-anon-test-information-tab

https://dev.azure.com/dnceng/public/_build/results?buildId=1871584&view=ms.vss-test-web.build-test-results-tab&runId=49033896&resultId=173719&paneView=dotnet-dnceng.dnceng-anon-build-release-tasks.helix-anon-test-information-tab

[krwq]

@jakobbotsch this seems like it happened in the same run 2min apart from each other (7/11/2022, 10:18:42 AM & 7/11/2022, 10:16:39 AM) but machines do in fact look like they're different: a000XKI & a000XJR. I'm curious if there was some external factor perhaps.

I'd be interested in seeing if we have more instances of this before investigating.

[jakobbotsch]

libraries-jitstress runs many scenarios (different environment variables) and triggers multiple helix job runs simultaneously, so it is not surprising that the timestamps are close to each other since indeed the pipeline run that triggered them is the same.

[jakobbotsch]

I do see pretty significant memory usage in this test when running it locally:

[krwq]

we should either fix memory consumption or disable memory heavy test cases in 7.0

[eiriktsarpalis]

Since this concerns unit testing for the source generator, wonder whether this could be related #71653

cc @CyrusNajmabadi

[danmoseley]

Is it important to run the generator tests on a checked runtime? If not why not just disable them [SkipOnCoreClr("Uses too much memory", ~RuntimeConfiguration.Release)] on each class. It looks like it might work on the whole assembly if you need it to.

[karelz]

Note: It has been problem only in 3 builds in last 60 days (see top post). Removing the blocking-clean-ci label for now.

[karelz]

Actually, Kusto shows more failures -- see updated top post. Adding the label back.
If it does not happen again for 1-2 weeks, we can remove it again.

We need to disable for chk CLR as suggested above

[jakobbotsch]

We are still hitting this on jit pipelines that run libraries tests frequently.
For example, our latest weekend libraries-pgo run hit this 9 8 times in separate runs: https://dev.azure.com/dnceng/public/_build/results?buildId=1913659&view=ms.vss-test-web.build-test-results-tab

Note that I believe the x86 host is not large address aware, so the 1.8 GB memory usage in my screenshot above is quite close to the 2.1 GB limit on x86.

[danmoseley]

@krwq what do you propose here?

[karelz]

Removing 'blocking-clean-ci' - the tests were disabled on non-Release runs in PR #73181
