AF_INET sockets utilize AF_INET socket data buffers only when the process is configured on a Legacy TCP/IP address.
If the process is configured on a Parallel Library TCP/IP, TCP/IPv6, or CIP address, then AF_INET sockets do not utilize
AF_INET socket data buffers.
Table 8 lists the bounded resources of the OSS File System and their per-processor limits. These
resources are viewable in both SCF and the HP NonStop Measure performance monitor, except
where the name is listed as N/A.
