agent's hourly cost pull hit the 10 concurrent query limit on At

Not specified by the original author.

TL;DR

The agent fires many Athena queries at once and hits the account's concurrent query limit, so queries queue or fail and the dashboard goes stale. Serialize the cost queries (run them sequentially), combine them where possible, and cache results between pulls. Athena's concurrency limit is per account; the agent must stay under it.

Error

agent's hourly cost pull hit the 10 concurrent query limit on Athena  -  the dashboard went stale

Steps

1. Confirm the throttle: Athena shows queued or rejected queries during the pull window. Expected: the concurrency limit is the bottleneck.
2. Change the agent to run cost queries sequentially instead of in parallel. Expected: at most one or two queries run at once.
3. Combine multiple small queries into fewer, larger ones where the logic allows. Expected: the query count drops.
4. Cache the results and serve the dashboard from cache; only re-query on schedule. Expected: the dashboard stays fresh without repeated bursts.
5. Re-run the pull cycle and verify all queries complete. Expected: no throttling, current data.

When to use

• Athena cost queries hit the concurrent query limit.
• Parallel query bursts throttle.
• The dashboard goes stale after throttles.

When not to use

• Queries fail on syntax (a query bug).
• The limit is on data scanned (a query-efficiency problem).
• One slow query blocks the rest (optimize that query).

Tool compatibility

AWS Athena (current 2026 releases).

Variant phrasings

"too many concurrent queries" on athena

Serialize the queries.

parallel cost queries throttled

Run sequentially and cache.

athena burst during the hourly pull

Fewer, bigger queries plus caching.

Why it happens

Athena's concurrent query quota is shared across the account, and an agent that parallelizes aggressively consumes it in one burst, starving its own queries and anyone else's. Cost data changes slowly, so the burst buys nothing: sequential queries with caching deliver the same freshness without the throttle. Concurrency is a resource to budget, not a speed lever to max out.

TL;DR

The agent pulls Cost Explorer every hour with no retry logic, so the first throttle kills the pull and the dashboard goes stale. Add exponential backoff with jitter on RequestLimitExceeded, honor the API's rate limits, and consider whether hourly granularity is needed (billing data updates daily anyway). The throttle is the API protecting itself; the agent must cooperate.

Error

"RequestLimitExceeded" on ce:GetCostAndUsage during the agent's hourly pull  -  backoff missing

Steps

1. Confirm the throttle in the agent log: RequestLimitExceeded on ce:GetCostAndUsage with no retry. Expected: the error and the missing retry are visible.
2. Add exponential backoff with jitter on throttling errors. Expected: the agent retries with growing delays instead of dying.
3. Reduce the pull frequency if hourly is unnecessary: Cost Explorer data refreshes roughly daily, so daily pulls often suffice. Expected: the call volume drops well under the limit.
4. Cache results and serve the dashboard from the cache between pulls. Expected: the dashboard stays fresh without extra API calls.
5. Re-run the pull cycle and verify it completes through throttles. Expected: the data lands reliably.

When to use

• Hourly Cost Explorer pulls hit RequestLimitExceeded.
• The agent has no backoff on throttling.
• The dashboard goes stale after throttles.

When not to use

• The error is AccessDenied (a permission problem).
• The data is stale for other reasons (a pipeline problem).
• Real-time cost data is genuinely required.

Tool compatibility

AWS Cost Explorer API ce:GetCostAndUsage (current 2026 releases).

Variant phrasings

cost explorer throttled on a schedule

Back off and reduce frequency; the data is daily anyway.

hourly pull dies on RequestLimitExceeded

Add retry with backoff and jitter.

dashboard stale after the pull failed

Cache the last good pull and retry the fetch.

Why it happens

Cost Explorer is a shared, rate-limited API, and billing data underneath it updates on a daily cadence, so hourly pulls pay throttle risk for no freshness gain. Agents that poll aggressively without backoff hit the limit and then fail hard instead of waiting. Backoff plus a sane cadence (daily, or hourly with caching) keeps the agent under the limit permanently.

TL;DR

Fix this in Synonym list agent by acting on the exact symptom first: read the rate limit response and wait for the stated reset, lower the request concurrency for synonym writes, save the pairs already written, and resume with only the remaining pairs. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

API rate limit hit mid workflow when the agent tried to rebuild the search synonym list, quota failed

Use this when

• Work in Synonym list agent shows this exact symptom: API rate limit hit mid workflow when the agent tried to rebuild the search synonym list, quota failed.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Synonym list agent, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: read the rate limit response and wait for the stated reset, lower the request concurrency for synonym writes, save the pairs already written, and resume with only the remaining pairs. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Synonym list agent that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

How to fix - API rate limit hit mid-workflow when agent tried to rebuild the search synonym list error failed quota

The how to phrasing for the same problem in Synonym list agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Synonym list agent troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

The rebuild wrote pairs in a fast burst that exhausted the quota part way through, and without a saved position the retry started again and hit the same wall.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Synonym list agent at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.
