WU_E_DS_SESSIONLOCKMISMATCH
WU_E_DS_SESSIONLOCKMISMATCH means a data-store lock operation was associated with a different session from the one that held the lock. It is a session-lifecycle problem, usually relevant to callers of Windows Update components.
For developers
- Ensure the same session acquires and releases the data-store lock.
- Do not reuse lock or table handles after disposing, resetting, or recreating a session.
- Look for concurrent access paths that can cross session boundaries.
Diagnose ownership, not network connectivity
The error reference describes a table that cannot be closed because it is not associated with the session. That makes the useful timeline the lifetime of the WUA session and the objects created under it. If a service recreates a session after failure or shutdown, cached COM objects from the previous session should not be fed into the new workflow.
Instrument creation and disposal of update sessions, asynchronous callbacks, and worker-thread handoff. The failure is especially informative in custom WUA clients that run several searches or installations concurrently: correlate the table or operation with the session that created it and verify that cleanup executes on the same logical ownership path.
