Renovate "PR limit reached" (prConcurrentLimit) in CI
Renovate limits how many PRs it keeps open and how many it creates per hour, via prConcurrentLimit and prHourlyLimit. When a limit is hit, it defers the rest and logs "PR limit reached", which can look like Renovate stalling.
What this error means
Renovate logs "PR limit reached" or "Skipping branch creation as prConcurrentLimit reached", and expected update PRs do not appear until open ones are merged or closed.
INFO: Skipping branch creation as prConcurrentLimit (10) has been reached

Too many open Renovate PRs
The number of open Renovate PRs reached prConcurrentLimit, so new branches are deferred until some close.
The hourly creation limit throttled new PRs
prHourlyLimit caps how many PRs are created per hour to avoid noise, spreading updates over time.
How to fix it
Raise or remove the limits deliberately
- Decide how many concurrent PRs the team can review.
- Set
prConcurrentLimitandprHourlyLimitaccordingly (0 disables the cap). - Merge or close stale Renovate PRs to free slots.

"prConcurrentLimit": 20,
"prHourlyLimit": 4
}Reduce PR volume with grouping
Group related updates so fewer PRs are needed, keeping you under the limit without raising it.
How to prevent it
- Tune
prConcurrentLimit/prHourlyLimitto review capacity. - Merge or close Renovate PRs promptly to free slots.
- Group updates to cut total PR count.
