It's operating system dependent.

  • For Windows, look here for the MaxConnections entry.

  • For Linux, look here as the comment on question says.

That'll be governed by the number of client-side ports available to your process (that i, when you open a connection to a remote host/port combination, you will also require a port at your end).

The total of client side (or ephemeral) ports will be made available to all the processes on your machine. So it depends on what else is currently running.

The number of ports and the configuration is OS dependent. Just Google for 'max number of ports' plus your OS.

This is an operating system limit.

Basically each socket will require a file descriptor (in Linux/Unix terms; it's probably equivalent in Windows). The OS will have a per-process file descriptor limit (say 250-1000) and that'll be the upper limit.
