DB_E_OUTOFSPACE
Meaning
Windows documents DB_E_OUTOFSPACE as “Object cannot be created at this URL because the server is out of physical storage”. In this case, the provider cannot create the URL-addressed object because backing physical storage is exhausted.
Conditions that specifically lead to the result
- Cause 1: the target volume or quota is full.
- Cause 2: provider metadata space is exhausted despite free data bytes.
- Cause 3: temporary or transaction space cannot accommodate creation.
Relevant contract
Investigation of this result should start with the binder or session, normalized URL, requested GUID/object type and DBBINDURLSTATUS result.
Diagnostic sequence
- Identify the exact failing stage: the provider cannot create the URL-addressed object because backing physical storage is exhausted.
Evidence to collect
A useful diagnostic event records provider CLSID and version, process architecture, interface IID and method, object correlation ID, transaction state and the immediately preceding HRESULT. When recording diagnostic data involving URLs containing credentials, tenant paths and remote object names, use types, lengths, hashes or redacted identifiers rather than secrets or complete business data.
- Evidence 1: free space and quota at the authoritative server.
- Evidence 2: requested object size or growth estimate.
- Evidence 3: provider-native storage and transaction diagnostics.
Corrective actions
- Action 1: free or expand the correct storage pool.
- Action 2: enforce quotas and capacity alerts before creation.
- Action 3: clean abandoned temporary objects only through supported management paths.
Practical scenario
A repository has free client disk but its server quota is exhausted; increasing the server allocation resolves it.
Retry and recovery
Retry rule: retry after confirmed capacity has been restored.
Difference from nearby HRESULT values
E_OUTOFMEMORY concerns process memory allocation, while DB_E_OUTOFSPACE concerns provider backing storage for the resource.
