Nope. The larger number looks to be more or less correct.
One thing that happened early this morning was unusual. HP's monthly diagnostic kicked in. But I was running another program overnight. It and the HP program combined to bring the computer to a crawl (I guess it's hard to do memory tests when other programs are using huge chunks of memory) by the time I woke up and looked at it. Maybe SIML got lost in the shuffle.
