Spatial Analyst:  Extract Values To Points Tool.  Memory issues?

Hi all.  I've built a model to extract value from 31 rasters and store those values in a point table.  The model adds the raster value field to the point table, adds a new field named after the raster, calcs the new field to be equal to the value field, then deletes the value field and moves on to the next raster.  It makes it through 29 rasters and then gives me this error:

ERROR 010067: Error in executing grid expression. Assignment to non-variable
Failed to execute (Extract Values to Points (30))

It doesn't matter which order the rasters are in, it fails on number 30.  After that, I can't even manually run the Extract Values to Points Tool.  I have to close the model and ArcMap and then open it again.  Then I can run it manually, or run the model (up to raster 29), then it's stuck again.  I've checked all kinds of stuff, but I'm at a loss.  I've read up on the error in some closed threads, but the error it not related to spatial extent or coordinate systems.  Anyone have any ideas on possible solutions?  My paging size nearly 6gb and my memory is 4gb.  By the way, the points coverage is only 1000 points.
