MQ_ERROR_SIGNATURE_BUFFER_TOO_SMALL

Recovery rules

Allocate from the reported signature size and repeat a non-destructive retrieval.

Differences that matter

The condition is not evidence of low system memory. It describes the capacity and representation of one caller-owned output area. Code-specific condition: digital-signature output buffer.

Practical scenario

A diagnostic collector encounters it. It uses the returned required length, keeps the operation non-destructive, and retries with correctly typed storage.
