OSS_MEM_ERROR
OSS_MEM_ERROR (0x8009300E) is an OSS ASN.1 runtime result for memory access violation in codec execution. The runtime detected or trapped an invalid access, often caused by a bad pointer, corrupt value object, wrong ABI, or earlier overwrite. Because crash or exception address and call stack 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 module architecture, calling convention, and compiler settings, 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 memory access violation in codec execution 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 lifetime of every caller-owned buffer; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Test one variable at a time
- reproduce with page heap and full symbols
- test a freshly constructed minimal PDU
- disable custom allocators only as an isolation step
Build a useful capture
| Record | Diagnostic value |
|---|---|
| crash or exception address and call stack | Locates the concrete message, allocation, module, or API boundary |
| module architecture, calling convention, and compiler settings | Separates payload-dependent behavior from build and process state |
| lifetime of every caller-owned buffer | Makes the comparison reproducible without rewriting the original artifact |
Neighboring statuses: the result
OUT_MEMORY is a refused allocation; MEM_ERROR indicates that an address was not safe to access.
Keep the original bytes or object graph unchanged while testing reproduce with page heap and full symbols. A change in module architecture, calling convention, and compiler settings after reload, plugin replacement, restart, or schema deployment is evidence about runtime state, not permission to discard the reproducer. When lifetime of every caller-owned buffer points to one message, retain a cryptographic hash and the smallest safe sample instead of logging certificate, subscriber, credential, or private-key material.
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 crash or exception address and call stack can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use module architecture, calling convention, and compiler settings together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Decision matrix
| Controlled observation | Conclusion it supports |
|---|---|
| reproduce with page heap and full symbols | A changed outcome isolates the first proposed control instead of a blind retry |
| crash or exception address and call stack differs between success and failure | The difference localizes the memory access violation in codec execution 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
Find the first corruption or ABI mismatch and verify under memory instrumentation, not by catching and ignoring the status. A recovery test built around reproduce with page heap and full symbols 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 crash or exception address and call stack now satisfies the codec contract.
