CI_OUT_OF_INDEX_IDS
CI_OUT_OF_INDEX_IDS — 0xC0041805
A productive reading of exhausted Indexing Service index identifiers begins at the component boundary where the catalog cannot allocate another internal index ID from its available identifier space.
Place in the component lifecycle
Catalog partitions, indexes, identifiers, merges, and on-disk versions are internal storage structures. In the context of exhausted Indexing Service index identifiers, supported catalog administration and rebuild paths are safer than copying or editing individual files. Locate the first component changing state in this condition and distinguish later summary errors.
Important boundary. This is internal catalog-resource exhaustion, not a missing filesystem file or ordinary query limit. Record the exact constant and returning API.
Build a reliable incident timeline
| Incident fact | What it separates |
|---|---|
| Catalog statistics, index/word-list counts, merge history, and service uptime | Shows whether the first inconsistency arose during filtering, storage, administration, or enumeration. |
| Pending deletes, shadow indexes, failed merges, and configured limits | Ties the result to one catalog, source document, filter, or query object. |
| Disk space and resource-pressure events | Separates catalog state from source data, filter output, and client lifecycle. |
| Behavior of a newly created catalog with the same source scope | Provides a stable before/after comparison for rebuilding or correcting the index path. |
Preserve the smallest reproducible evidence set and remove document content or access-control details before sharing diagnostics.
Tests that change one variable
- Force or schedule a supported master merge after preserving statistics. Retain a known-good document or query so a broad catalog rebuild is not mistaken for repair of the reported failure.
- Test a small fresh catalog to separate global service from catalog exhaustion. Record the first filter, catalog, merge, query, or enumeration result that changes.
- Monitor identifier/index counts during controlled ingestion. Keep source bytes, scope, filter version, and unrelated catalog settings fixed.
Stop after the first comparison that moves the boundary and diagnose the replacement catalog or query status independently.
Interpretation boundaries
- Known-good comparison succeeds: isolate the production object or configuration associated with the failing operation.
- Same failure on the control: investigate the shared catalog, storage, filter-host, or query layer before changing source documents.
- Different status after one change: preserve both results; the first rejected condition was removed, but the operation is not yet proved complete.
Repair and regression proof
Correction: Resolve failed merges or catalog growth and rebuild the derived catalog when identifier state cannot be reclaimed safely. Keep the original catalog configuration, source inventory, filter identity, query definition, and event sequence so the change can be reversed and explained.
Accept the repair only when index counts stabilize through repeated ingestion/merge cycles and new documents receive IDs without recurrence. Repeat the original supported operation under the original identity and object state; a new catalog, different source scope, or replacement filter is useful comparison evidence but not final regression proof.
