OSS_ACCESS_SERIALIZATION_ERROR
OSS_ACCESS_SERIALIZATION_ERROR (0x80093013) is an OSS ASN.1 runtime result for failed serialization of shared OSS runtime state. On the legacy Windows runtime path, access to global data could not be serialized correctly in a multithreaded process. Because thread IDs entering the codec concurrently 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 lifetime and sharing of OssControl instances, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Interpretation at runtime
At the failed serialization of shared OSS runtime state 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 initialization and shutdown ordering; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Diagnostic record
| Record | Diagnostic value |
|---|---|
| thread IDs entering the codec concurrently | Locates the concrete message, allocation, module, or API boundary |
| lifetime and sharing of OssControl instances | Separates payload-dependent behavior from build and process state |
| initialization and shutdown ordering | Makes the comparison reproducible without rewriting the original artifact |
Small experiments with high signal
- run one call at a time as an isolation control
- give each supported context the documented ownership model
- remove codec teardown while worker calls remain active
Keep the original bytes or object graph unchanged while testing run one call at a time as an isolation control. A change in lifetime and sharing of OssControl instances after reload, plugin replacement, restart, or schema deployment is evidence about runtime state, not permission to discard the reproducer. When initialization and shutdown ordering points to one message, retain a cryptographic hash and the smallest safe sample instead of logging certificate, subscriber, credential, or private-key material.
Avoid the wrong workaround: the result
This code concerns synchronization around runtime-global state; MUTEX_NOT_CREATED identifies failure to create the primitive used for that serialization.
Decision matrix
| Controlled observation | Conclusion it supports |
|---|---|
| run one call at a time as an isolation control | A changed outcome isolates the first proposed control instead of a blind retry |
| thread IDs entering the codec concurrently differs between success and failure | The difference localizes the failed serialization of shared OSS runtime state 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 |
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 thread IDs entering the codec concurrently can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use lifetime and sharing of OssControl instances together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Proof of recovery: the result
Establish deterministic initialization, call ownership, and shutdown, then stress the same workload with concurrency enabled. A recovery test built around run one call at a time as an isolation control 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 thread IDs entering the codec concurrently now satisfies the codec contract.
