The tests-slow integration job has been hanging for hours on the self-hosted ARC runner. The cause is test_solve_cmip7_aft, which runs an end-to-end solve --timeout 3600 that executes ilamb diagnostics through the LocalExecutor. ilamb opens reference fields without dask chunks, so a lazy surface slice still materialises the whole multi-GiB ocean field; under the runner's synchronous dask scheduler these executions run for hours and approach the executor's per-task timeout, leaving the job stuck until GitHub's 6h wall.

This skips the test until ilamb3 loads references lazily. The skip reason documents the root cause and the re-enable condition so it is not a silent disable. The separate memory fix (BLAS thread caps + 40Gi) already resolved the earlier OOM signature on this job.

Review Change Stack

Warning

Review limit reached

@lewisjared, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 55 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
