"Decompression overran buffer (179)" error when connecting to database

By: Borland Staff

Abstract: Backup was created via file copy instead of transportable backup format

After moving a database file from a Windows machine to a NetWare server, the following error is
generated upon attempting to connect:

Internal gds software consistency check (decompression overran buffer (179))

The information in this article applies to:
* InterBase 4.x
* InterBase 5.x

Most likely the database was either straight file copied between the two _different_ platforms or a
non-transportable backup was restored from the Windows machine to the NetWare server.  In
either case, the database should be backed up as non-transportable and then restored.

Note: This error may even occur on the same operating system if the file systems are of different
types (for example, FAT16 and NTFS).

Note: A similar error ("internal gds software consistency check (wrong record length (183))") may
also occur for the same reason and the same steps above can be used to resolve it.
