Your SCO OpenServer system uses the STREAMS mechanism to support TCP/IP and other network protocols such as IPX/SPX. You should ensure that you provide an appropriate number of STREAMS resources for TCP/IP and IPX/SPX; without them, performance may suffer or the system may hang.
Run the netstat -m command to display STREAMS memory usage:
