These are informational messages that indicate the you do not have 
spatial indexes on some of your shape files -- these would be the 
filename.qix. You should run shapetree on every shape files.

If you don't, then you get these messages and mapserver has to either 
do a linear search of the shape file or build a temporary shape tree. 
This happens on every mapserver hit so adding the shapetree files can 
improve performance maybe significantly depending on your set up.
