What does HRESULT 0x87AF0007 (SQLITE_E_NOMEM) mean?

SQLITE_E_NOMEM

SQLITE_E_NOMEM corresponds to SQLite SQLITE_NOMEM. A memory allocation required by SQLite failed.

What to check for SQLITE_E_NOMEM

• Measure process memory limits, container limits, address-space pressure, and the size of result sets or bound BLOB values.
• Check application-configured SQLite heap limits or custom allocators before assuming a machine-wide out-of-memory condition.
• Avoid retrying a memory-intensive query unchanged; limit batches, stream data, or reduce working-set requirements.
