I don't know if you will find this helpful at all, the Core Bluetooth spec defines that error as:

2.40 INSTANT PASSED (0x28) The Instant Passed error code indicates that an LMP PDU or LL PDU that includes an instant cannot be performed because the instantwhen this would have occurred has passed.

The section on the error codes specifically states that they basically won't go into detail on what exactly can trigger an error status because they can be implementation dependent. That said, I think you can read into the explanation that some sort of PDU is being processed after the time it required to be processed. I have no idea on how you would avoid this.
