Re: Consistent CI failure in job nightly-i386-linux-deb9-validate

Sure, in which case pls revert it. Apologies for the impact, though I'm still a bit curious, the i386 job did pass in the original MR. On Wed, Sep 28, 2022 at 1:00 PM Bryan Richter wrote:

Yep, it seems to mostly be xz that is running out of memory. (All recent builds that I sampled, but not all builds through all time.) Thanks for pointing it out!

I can revert the change.

Hi Bryan,

This may be an unintended fallout of !8940. Would you try starting an i386 pipeline with it reversed to see if it solves the issue, in which case we should revert or fix it in master?

Hi all,

For the past week or so, nightly-i386-linux-deb9-validate has been failing consistently.

They show up on the failure dashboard because the logs contain the phrase "Cannot allocate memory".

I haven't looked yet to see if they always fail in the same place, but I'll do that soon. The first example I looked at, however, has the line "xz: (stdin): Cannot allocate memory", so it's not GHC (alone) causing the problem.

As a consequence of showing up on the dashboard, the jobs get restarted. Since they fail consistently, they keep getting restarted. Since the jobs keep getting restarted, the pipelines stay alive. When I checked just now, there were 8 nightly runs still running. :) Thus I'm going to cancel the still-running nightly-i386-linux-deb9-validate jobs and let the pipelines die in peace. You can still find all examples of failed jobs on the dashboard:

https://grafana.gitlab.haskell.org/d/167r9v6nk/ci-spurious-failures?orgId=2&from=now-90d&to=now&refresh=5m&var-types=cannot_allocate

To prevent future problems, it would be good if someone could help me look into this. Otherwise I'll just disable the job. :( _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
