Operational intent

What caused this production RAG incident?

Production incident postmortems: symptom → root cause → remediation → prevention, with trace/metric evidence and blast-radius analysis. Operational failure intelligence — trace evidence, eval regressions, and remediation chains with enterprise explainability (expert timestamps as corroboration only).

Operational failure intelligence

See the failure chain

Incident chains with trace evidence, eval regressions, config diffs, and remediation intelligence — expert timestamps corroborate hard citations, not replace them.

RAG incident root cause

Symptom
Hallucination rate 3.2× post-deploy; empty-context retrieve spans spike
Root cause
Metadata filter dropped boundary overlap chunks; overlap 128→32
Remediation
Rollback filter deploy, restore overlap=128, Phoenix faithfulness gate
Prevention
Canary eval gate on overlap + filter diff before prod rollout

Config evidence

  • chunk_overlap: 128→32
  • metadata filter v2
  • top_k: 20

Trace / metric evidence

  • faithfulness: 0.91 → 0.54

Why this answer won: Incident chain symptom→root cause→remediation with trace/metric hard signals; production_rag_failure_incidents contract.

Rejected: Excluded: generic “AI safety” clip with no config diff or incident timeline.

query: "production rag failure incident"

Answer

Production RAG failure incident: symptom empty context → hallucination after chunk_overlap=128 retrieval miss; root cause boundary chunks dropped postmortem; remediation reindex rollback top_k=20; faithfulness metric drop in retrieve span trace; indexed/verified expert timestamp for production_rag_failure_incidents; expert moment paired with hard doc citation (Arize postmortem).

Symptom
Hallucination rate 3.2× baseline post metadata-filter deploy; empty-context retrieve spans spike on high-traffic tenant.
Root cause
Metadata filter bug dropped boundary chunks after deploy; embedding model version skew
Remediation
Rollback filter deploy, restore overlap=128, reindex affected namespace, enable Phoenix faithfulness gate on canary before full rollout.

FAQ

What belongs in a production RAG incident postmortem?
Symptom timeline, retrieve/generate span anomalies, config diffs, faithfulness metrics, tenant blast radius, and verified remediation steps.
How do you avoid generic incident summaries?
Answers require hard signals — config knobs, metrics, trace IDs, and remediation verbs — filtered by operational truth governance.
Can I use this for enterprise RAG?
Yes — responses include enterprise explainability fields: severity, rollback complexity, and multi-tenant impact when evidence supports it.
Who owns RAG incident postmortems?
Platform SREs and ML on-call engineers running production copilots, agents, or internal RAG search.
