Weird behavior with locks during delete.
I'd say you are hitting a bug. It should not be blocking on any lock since you have DEF_LOCK_MODE set to ROW so row level locking should not be locking out row 2 when row 1 is being deleted. That's the first problem. Second is that, yes, the lock wait 10 should hold the error for…
