Severe error about missing raster band wavelength properties

[AndyWells]

I am troubleshooting some slowness with a map service of imagery. The clients are displaying this service a little bit slower than the older imagery. Both services were configured exactly the same. In looking at the logs, the server is constantly getting the severe error:

There is an error during the draw Southside_12inch_Mosaic.sid (1.) Missing raster band wavelength properties,(2.) Missing raster band wavelength properties,(3.) Missing raster band wavelength properties.

I'm not sure if this is contributing to the display issues, but the older service never had this error. Does anyone know what this means, and what I can do to fix it? Thank you.
