Cause
This error occurs if a problem is encountered while reading from the input file in a schema load. The error may have been caused by some other application corrupting or deleting the file during the load.
If the file is on a LAN server volume, the LAN connection may have been lost during the load.
Action
Check that the file is still present and has not been corrupted. If the file is on a server LAN, check that the LAN connection is still valid and that the file is accessible.
