OSS_MEM_MGR_DLL_NOT_LINKED
OSS_MEM_MGR_DLL_NOT_LINKED (0x80093026) is an OSS ASN.1 runtime result for OSS memory-manager DLL absent. The runtime configuration expects its optional memory-management component, but the module cannot be loaded. Because allocator callbacks and selected memory mode 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 and dependency chain, 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 OSS memory-manager DLL absent 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 allocation/free ownership across DLL boundaries; 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 the documented default allocator
- trace every allocation and matching free in a test
- Check that one CRT does not free another module’s block
Build a useful capture
- allocator callbacks and selected memory mode
- module architecture and dependency chain
- allocation/free ownership across DLL boundaries
Neighboring statuses: the result
Substituting arbitrary allocation functions can create cross-module ownership faults even when allocation itself succeeds.
Instrumentation
Where allocator callbacks and selected memory mode can expose sensitive content, a hash plus a bounded structural excerpt is safer than the complete payload. Use module architecture and dependency chain together with OSS module paths and versions logged once per process so packaging differences can be correlated without flooding normal diagnostics.
Verify the repair: the result
Deploy the matching memory manager or configure one documented allocator contract for the entire value lifecycle.
