The last Create is transitioning the oplock state to BREAK_TO_TWO_TO_NONE while the previous oplock BREAK_TO_TWO is still unacknowledged.
This explains why the ack to Level2 returned the error.
>From server implementation perspective, you can either explicitly ack straight to None (FSCTL_OPLOCK_BREAK_ACK_NO_2) or ack and end up with either Level2 or None, depending on the state of the oplock when your ack shows up (FSCTL_OPLOCK_BREAK_ACKNOWLEDGE).

Let's me know whether this helps.
