We have a Firebird 1.0 database that has exceeded 6GB. Since the
server is running Windows 2000 with NTFS as the file system, we're
trying to restore a backup made with GBAK to a single file using the
Localhost connection.

Whenever the file gets to 4GB, the server shuts itself down and the
restore fails with a lost connection. The server log lists the
following problems with the same timestamp:

INET/inet_error: accept errno - 10093
INET/select_wait: select failed, errno = 10093
SRVR_multi_thread/RECEIVE: error on main_port, shutting down

Then, 2 seconds later:

C:\Program Files\Firebird\bin\ibserver.exe: terminated abnormally (-1)

The guardian then restarts the server.

This always happens at the 15,700,000th record and the resulting .gdb
database file is exactly 4GB in size.

Can't a database that's larger than 4GB be restored into a single
file database?
