We???re trying to process a grid in ArcGIS 10, and we???re getting the following error about two hours after running the process:

Error 999999 Error executing function.

File read/write error occurred.

File read/write error occurred.


Failed to execute (select layer by location)

We???re using a 2 CPU VM with 8GB of RAM running on 64-bit Windows 7 with 50 GB of disk space.  When the process stops, there are 34 GB of disk space remaining, so it doesn???t appear to be a disk space issue.  It doesn???t appear to be a permissions issue either.
The (file based) geodatabase is 14.4 GB and it contains almost 88 million grid cells.

Has anyone come across this before?
