Network Analyst - Closest Facility Tool Discrepancies

Using the closest facility tool, I've noticed that when I try to figure out the shortest distance between two nodes there are some discrepancies.  Case in point, I'm trying to connect nodes to several transit locations - trying to see which routes are closest to transit in the surrounding communities.  I have 10 transit stations (Facilities) and about 700 nodes (Incidents).  Some Incidents are not being routed to the closest Facility.  There's no hierarchy in my network dataset, it's just a bare bones one (just using TIGER files in which I ensured its topological accuracy and checked for dangling nodes).  Any thoughts would be greatly appreciated!  It's only happening a few times out of hundreds so it's not terrible but still a little puzzling.
