I guess that it's because keepalive doesn't work as expected in some cases. For example, if the network outage happens before a client sends some packets, keepalive doesn't work, then it would have to wait for a long time until it detects the outage. This is the specification of linux kernel. So a client should not have excessive expectations of keepalive, and should have another timeout like QueryTimeout of JDBC.
