STATUS_OPLOCK_SWITCHED_TO_NEW_HANDLE
The oplock is now associated with another handle
This status describes oplock ownership rather than file data failure. The oplock that was tracked through one handle has moved to another handle, so later break or close processing must follow the new association.
It matters in filter drivers and redirectors that keep per-handle state. If the diagnostic log follows only the original handle, it can wrongly conclude that the oplock disappeared or was leaked.
What to inspect
- Track file object and handle identity separately.
- Correlate the status with duplicate, reopen, or redirector state transitions.
- Confirm that cleanup paths update the handle that owns oplock notification state.
