Looks like the smoke tests now fails on step 60 (phoenix) because the restserver gets OOMKilled and then doesn't have the /tmp/test_phoenix.sh script anymore. After increasing the restserver memory budget to 1GiB it still seems to fail for some unclear reason, but only when running without --skip-delete.

Tests pass for me if I up the resource limits:

But that's pretty concerning to me, is that indicative of a larger problem with our default resource limits here?

Thanks, applied.
