Why an epmd process doesn't exit?

问题

Is it a bug or a feature that epmd process still exists after I exit from an erlang shell ?

回答1:

It is quite normal: EPMD is a host daemon process. Its presence is required when one intends to use distributed nodes. It is also useful when just using many nodes on the same machine.
