Do you have a proposed patch for this issue as you seem to be able to
reproduce this?

Wait, this is a fake problem:

You are manually injecting faults.  That's not a normal operation.  If
you can reproduce this without fault injection, please let us know.

Or propose a patch to resolve this?

thanks,
