NTE_NO_MEMORY
NTE_NO_MEMORY means that the cryptographic provider could not allocate the memory required for the requested operation. It can be a genuine resource-exhaustion condition or a symptom of unusually large input or unreleased cryptographic objects.
What to check
- Record process memory pressure, input sizes, concurrency, and provider-specific resource usage at the failure point.
- Release cryptographic contexts, keys, and buffers according to the API ownership rules.
- Avoid unbounded retries; reduce the request size or restore capacity before trying again.
