Warning

Rate limit exceeded

@MahnoorAsghar has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 21 minutes and 45 seconds before requesting another review.

Your organization is not enrolled in usage-based pricing. Contact your admin to enable usage-based pricing to continue reviews beyond the rate limit, or try again in 21 minutes and 45 seconds.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.

The default controller-runtime exponential rate limiter has a maximum
delay of 1000 seconds (~16 minutes).  During BMO startup there is a
brief race between the reconcile loop becoming active and BMO's own
validating-webhook Service endpoint being propagated: any BareMetalHost
reconciliation that triggers a webhook call in that window gets a
"no endpoints available" error.  A burst of such errors is enough to
drive the per-item exponential backoff to its ceiling, after which BMO
silently waits up to 16 minutes before attempting the next reconcile
even though the webhook has long since become reachable.

Replace the default rate limiter with one that is otherwise identical
but caps the per-item exponential delay at 30 seconds.  This bounds
the recovery window to at most one retry interval after the endpoint
is propagated, matching the behaviour of other Metal3 controllers.
