DB_E_OBJECTCREATIONLIMITREACHED

Exact value and result class

DB_E_OBJECTCREATIONLIMITREACHED has unsigned value 2147749481 (0x80040E69) and signed 32-bit value -2147217815. AllStat describes it as “Session cannot be created because maximum number of active sessions was already reached. Consumer must release one or more sessions before creating a new session object”. In this result, IDBCreateSession cannot create another session because the provider maximum is already active.

The high bit is set, so this result is a failure HRESULT. Its facility is 4 (FACILITY_ITF) and its low code is 3689 (0x0E69). These fields identify an interface-defined result family; they do not identify the provider instance, method, object generation or partial effects.

Evidence to collect

A useful this result event records provider CLSID and version, process architecture, interface IID and method, object correlation ID, transaction state and the immediately preceding HRESULT. When recording it data involving connection identifiers, account names and command activity, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.

  • Evidence 1 for it: active session count and configured maximum.
  • Evidence 2 for it: outstanding COM references by pool entry.
  • Evidence 3 for it: age and workload of sessions awaiting release.

Contract boundary

OLE DB session creation consumes provider resources and establishes transaction and object scope. Session limits include still-referenced sessions and dependent commands or rowsets, not only objects visible in application-level pools.

Investigation of this result should start with the data source object, active session count and all dependent COM references. Capture it before ADO, ATL,.NET or a database abstraction layer replaces the native HRESULT with a generic exception.

Conditions that specifically lead to it

  • Cause 1 for it: sessions remain referenced in a pool.
  • Cause 2 for it: commands or rowsets keep parent sessions alive.
  • Cause 3 for it: concurrent demand exceeds the provider or server limit.

Diagnostic sequence

  1. Capture raw 0x80040E69 and symbolic it at the native call boundary.
  2. Identify the exact failing stage for it: IDBCreateSession cannot create another session because the provider maximum is already active.
  3. Retrieve all OLE DB error records for it before another COM call replaces thread error information.
  4. Compare the live object state and provider-granted capabilities with the input that produced it.
  5. Reduce the operation to the smallest case that preserves the same session contract.
  6. Apply one evidence-backed correction for it and verify that the result is not merely replaced by a neighboring HRESULT.

Corrective actions

  • Action 1 for it: release dependent commands and rowsets before returning sessions.
  • Action 2 for it: bound pool size to provider capacity.
  • Action 3 for it: queue work or scale data sources rather than spin on creation.

Practical scenario

A pool leaks command references when requests fail; fixing cleanup frees sessions and restores creation capacity. Keeping it with the method and object state makes this scenario diagnosable instead of reducing it to “database error”.

Developer and operations guidance

Code handling it should release COM objects in ownership order, retain per-row, per-column or per-property statuses, and log granted capabilities rather than only requested options. While handling it, opaque values such as HACCESSOR, HROW, HCHAPTER, DBID components and provider handles must remain scoped to the object that issued them.

Operational dashboards for it should group by provider version, interface, method and normalized failure stage. A it event must not expose passwords, tokens, full connection strings, unrestricted command text or raw row contents.

Retry and recovery

Retry rule for it: retry after at least one active session and its dependents have been released. A it retry is safe only when the relevant input, object generation, capability or external state has changed. Before replaying a modifying call that returned it, determine whether rows, schema objects or URL resources were partially created or changed.

Do not turn it into an unbounded retry loop. Preserve cancellation for it and use a fresh provider object when the failed call may have left local state ambiguous.

Difference from nearby HRESULT values

DB_E_OBJECTOPEN reports an object blocked by dependents, while it reports exhausted session capacity. Telemetry and remediation for it should keep these outcomes distinct.
