Specifies the maximum number of connections that SPX can support. Decrease this value to conserve memory; increase this value if connections fail because no more devices or sockets are available. If the system offers NetWare print services, allow enough connections for the print server, each printer, and other NetWare servers serviced by the print server. You may also need to increase this value if the system is configured for NVT services. The default value is 100.
