Randomly errors in pipelines

It happens randomly that in pipelines we get errors of the form

• "The requested URL returned error: 502", see e.g., https://gitlab.dune-project.org/infrastructure/dune-nightly-test/-/jobs/212907
• "ERROR: Uploading artifacts as "archive" to coordinator... too large archive", see, e.g., https://gitlab.dune-project.org/infrastructure/dune-nightly-test/-/jobs/212080
• "WARNING: Uploading artifacts as "archive" to coordinator... failed", see, e.g., https://gitlab.dune-project.org/infrastructure/dune-nightly-test/-/jobs/212751

Another error comes from memory limitations.

With these errors large pipelines fail nearly every day. The questions is: can we do anything against it?
