Yep, that sounds like it. With very large apertures (1.8, 1.4) you can even have trouble keeping in focus an individual subject from front to back.

I had the same problem at a recent event I photographed. Still getting used to my 50 f/1.4 and was large aperature happy. I didn't get some of the shots I could have because I had the aperature opened up way too much. Looking back on it, I was at f/1.8 or so and I figure I should have been around f/2.8-f/4, maybe even smaller. Live and learn I suppose.

The "in focus" area runs from the point of primary focus into the foreground as well as into the background. So focusing on a target in the middle of the group is the best way to use lens DOF characteristics for sharp portraits. Here's a staircase shot using that principle. The shooting data was f/4.0 at 38.0mm on a d200 body.
