Jim,
I was aware of the NETSTAT POOLSIZE results; however, even there is
nothing that points me to what that *TCP Connections* mean nor is there
a value of 511 mentioned:
netstat poolsize
VM TCP/IP Netstat Level 540 TCP/IP Server Name: TCPIP
TCPIP Free pool status:
Object No. alloc No. free Lo-water Permit size

NETSTAT POOLSIZE may give you the information you want.
