more on the subject of filler popping

Wood floor filler generally loses its bond from movement, a loose board,
expansion and contraction, a nail beneath the filler moving, etc. Open
stable holes generally will stay. Good filler has good adhesion properties.

Thanks everyone for all the fantastic replies so far. It looks like
plugging the holes with a matching wood is the winning way to go. I've
got a couple of other ideas, can anyone tell me how they compare?

1. Use some sort of epoxy (sp?) with sawdust from the floor. I heard
that boat builder's often use this solution. I assume you'd still have
to drill the holes straight and perhaps in the end this still has the
chance of popping out?
