OSS_BAD_TABLE
OSS_BAD_TABLE (0x8009300F) is an OSS ASN.1 runtime result for corrupt encoder or decoder control table. The runtime cannot use the generated control information, usually because the OssControl object or table pointer has been damaged or initialized incorrectly. Because address and identity of the control table 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 result of the initialization function, then separate the encoded value from generated artifacts, call arguments, and the runtime package actually loaded by the process.
Avoid the wrong workaround: OSS_BAD_TABLE
NULL_TBL is specifically a null table pointer; BAD_TABLE means a non-null table fails integrity or interpretation checks.
Interpretation at runtime
At the corrupt encoder or decoder control table 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 write history for the OssControl storage; otherwise an outer certificate or security wrapper may hide the useful codec result behind a generic failure.
Diagnostic record
- address and identity of the control table
- result of the initialization function
- write history for the OssControl storage
Small experiments with high signal
- Create a new control object in isolated storage
- Compare table bytes with the deployed artifact
- remove post-initialization writes to the control structure
Instrumentation
Where address and identity of the control table can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use result of the initialization function 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
Treat generated control data as immutable, initialize once as documented, and replace any mixed or modified artifact.
