OSS_LIMITED
OSS_LIMITED (0x8009300A) is an OSS ASN.1 runtime result for implementation limit exceeded while decoding. A syntactically recognizable value exceeds a runtime capacity, such as an INTEGER magnitude, nesting depth, or representation supported by that build. Because value length, magnitude, and nesting at failure is central to this condition, Microsoft’s HRESULT range and the OSS Nokalva return-code documentation should be read together. Start the investigation by recording runtime edition and generated representation options, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
What the return code narrows down
At the implementation limit exceeded while decoding boundary, capture the first OSS function returning the value and note whether the operation was encode, decode, copy, compare, constraint validation, or trace setup. Preserve the selected PDU, encoding rules, and protocol limits expected by the application; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Build a useful capture
| Record | Diagnostic value |
|---|---|
| value length, magnitude, and nesting at failure | Locates the concrete message, allocation, module, or API boundary |
| runtime edition and generated representation options | Separates payload-dependent behavior from build and process state |
| protocol limits expected by the application | Makes the comparison reproducible without rewriting the original artifact |
Neighboring statuses: the result
A schema constraint violation is reported separately; LIMITED can arise even when the abstract ASN.1 type has no such narrow bound.
Test one variable at a time
- decode a value just below the observed boundary
- enforce a protocol quota before ASN.1 allocation
- compare another supported runtime build without changing schema
Instrumentation
Record the full 32-bit HRESULT and lower OSS return number together with operation direction, symbolic PDU, encoding rule, byte count, and generated-table identifier. Where value length, magnitude, and nesting at failure can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use runtime edition and generated representation options together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Keep the original bytes or object graph unchanged while testing decode a value just below the observed boundary. A change in runtime edition and generated representation options after reload, plugin replacement, restart, or schema deployment is evidence about runtime state, not permission to discard the reproducer. When protocol limits expected by the application points to one message, retain a cryptographic hash and the smallest safe sample instead of logging certificate, subscriber, credential, or private-key material.
Decision matrix
| Controlled observation | Conclusion it supports |
|---|---|
| decode a value just below the observed boundary | A changed outcome isolates the first proposed control instead of a blind retry |
| value length, magnitude, and nesting at failure differs between success and failure | The difference localizes the implementation limit exceeded while decoding boundary before unrelated settings are changed |
| An independent decoder accepts the same artifact | Inspect generated schema, selected rules, ABI, and optional OSS modules before declaring the bytes invalid |
| A fresh control object changes the outcome | Investigate initialization, lifecycle, allocator ownership, configuration mutation, and concurrent access |
Verify the repair: the result
Choose a representation that supports the required range or reject oversized inputs at the protocol boundary. A recovery test built around decode a value just below the observed boundary should replay the same operation under the same schema and encoding rule, retain one deliberately invalid control, and verify ownership and cleanup after both outcomes. Success after an unexamined retry is not proof that value length, magnitude, and nesting at failure now satisfies the codec contract.
