I removed the resolutions and extent_type from the URL and change size 
to the default of 256. I also stop and restarted my server. I am still 
getting the same messge. Here is my basemap conf:

[basemap]
type=MapServerLayer
layers=basemap
mapfile=/var/www/html/mapdata/rdubsmll.map
extension=png
bbox=-79.55334892, 35.50717788, -78.22326740, 36.26503708
resolutions=0.002213114009982047,0.001106557404326176,0.0005532787162146718,0.0002766397670557272,0.00013832010135122262,0.0000691605672361935,0.000034580698835992964,0.000017290349417996482,0.000008645270269927052,0.000004322795340797067
extent_type=loose
levels=10
srs=EPSG:4326
debug=on

I got the resolutions by converting scale values, I got from a mapserver 
app, that used the same mapfile, using 
OpenLayers.Util.getResolutionFromScale.
