Further information
1. In order to verify if the connection between a client and a server is still active, a
keep alive message is sent from the server to the client every
interval seconds. A server will consider the link is down (and close the connection) if no reply has been received after
maxfail+1
keepalive messages. Similarly, a client will close the connection to a server that has not sent any message for more than
interval*(maxfail+1) seconds.
2. Using value
0 for
maxfail disables the
keepalive mechanism.
3. This routine can only be called before any connection is created.
