how long before a process receives a socket closed message

Suppose you have an Erlang process which is handling a socket (gen_tcp/ssl) and the peer closes the connection.

How long does it take before the process receives a message like:

{tcp_closed, Socket}

or

{ssl_closed, Socket}

Is this amount of time specified somewhere in Erlang code or is it related to the system?

Solution

  • It should take one ping time of the network, unless congestion is present.
