Loading a raster catalog from workspace keeps crashing ArcCatalog

[LizCarter1]

I created a file geodatabase and a raster catalog within it.  I've been loading the raster catalog 'from workspace' and while it takes a while to load the raster sets I've got, it had been working.  In the last two days, even though I'm following the same process, I get the "ArcCatalog Application has stopped working".  I've tried loading smaller data sets but that isn't working either.

Any ideas?

When you add the rasters to the raster catalog are you choosing to create a managed raster catalog or unmanaged.  Unmanaged should continue to work, since you are not importing the rasters.  If you are choosing managed, then perhaps you are exceeding the limit of the geodatabase if you are choosing a personal or the total file size for a file geodatabase.  Bear in mind, if you are choosing to import .sids or other highly compressed files, then they will be uncompressed and create files that are much larger than the original based on the compression.  Perhaps you are either running out of room on the disk or within the personal geodatabase.  That is the most likely reason, otherwise, perhaps one of the rasters is not defined and the chosen projection will not accommodate all of the rasters.
