Renovate started failing with "kernel-out-of-memory"

[marcphilipp]

How are you running Renovate?

A Mend.io-hosted app

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

No response

Please tell us more about your question or problem

Recently, Renovate started failing with "kernel-out-of-memory" errors for https://github.com/junit-team/junit-framework. Looks like we need more memory?

Logs (if relevant)

There's nothing in the logs regarding the error, as far as I can tell.

Apologies for the delay - I can see that the last couple of weeks worth of jobs seem to be OK (please correct me if I'm wrong!) but we'll take a further look internally

[marcphilipp]

It somehow fixed itself. Maybe it only happens when updating the Gradle wrapper?

[jamietanna]

Correct - it looks like we hit the memory allowance (as you said) in i.e. https://developer.mend.io/github/junit-team/junit-framework/-/job/69c13eef-1f2e-4747-b62c-3cffbb7e2d01

It's possible to request increased resource usage (#33617) - would you like us to apply that to repositories in https://developer.mend.io/github/junit-team ?

[marcphilipp]

Yes, please! 👍

Hey Marc, we've now upgraded the JUnit org to the Community (OSS) plan, which entitles you to:

• 2 concurrent jobs per organisation (i.e. 2 of your 5 repos on the org will process concurrently)
• double memory (6GB)
• access to Merge Confidence Workflows - you'll be able to use matchConfidence to group PRs based on the Merge Confidence

Please give us a shout if you have any feedback, in particular on Merge Confidence Workflows!

Thanks! Would it be possible to add the ota4j-team organization as well (which is also maintained by the JUnit team)? Especially in https://github.com/ota4j-team/open-test-reporting, there are a lot of dependency updates that could benefit from matchConfidence. How does one get an API key to use the feature (which is needed according to the docs)?

[jamietanna]

Sure thing! We'll add them tomorrow 😄

Re API key, you don't need to manually request one for access - when using Mend Renovate Community Cloud, under the Community (OSS) plan, you get it automagically wired in:
