Thanks for the info! This happened when you had 2 spot instances running something, correct?

And the config is:

Hey CostlyOstrich36 I got another occurence of autoscaler crash with a similar backtrace, any updates on this issue?

I got the same issue as well last night.

oopsy bad chunk

Hi FierceHamster54 , is this an old autoscaler instance? What is the version? You can see the version when you're on the application and click on 'More' at the top left text area

This is an instance than I launched like last week and was running fine until now, the version is v1.6.0-335

Sure

Do you know what was the state of the experiments at the time?

Great, thanks! Looking into it 🙂

And there was still 2 instances running from the last pipeline run

Can you please add a larger chunk of the autoscaler log?

I was launching a pipeline run, but I don't remember having set the autoscaler to use spot instances (I believe the GCP terminology for spot instance is "preemptible" and I set it to false)

Another crash on the same autoscaler instance:
