Yes. SQL Server occasionally loses it's mind on such things. Over the last 16 years of using SQL Server, I've given up on trying to find the reasons. It appears to be because of spurious pips on the network when you have a waxing moon with the correct angular displacement to certain sunspots and the Red Wings are playing a home game on a rainy day but only during high tide and the coffee machine across the room is cycled. 😀
