There is a limit - the limits of your machines resources

Each connection requires a port to connect to (64k available port numbers)
and only one process can connect on or bind to a single port and then only
once.

Each port occupies one available file connection inside the process so a
process is limited to this maximum usually 1024 (changable using sysconfig?)

there is a limit to the number of processes running per user (not sure if
this applies to root)

each process takes up swap space so the number of processes is limited by
this

as to an OS limit on open TCPip connections I don't think there is a hard
maximum number
