I think in 8.x releases is no need to make any spacial close operation,
or at least You do not get notice, about it. Closing socket is enough.
E.g. JDBC driver closes connection, by closing socket. In 9 this changed
and I see many of such notices in log. Probably Your driver, as many
others, is written to close socket without backanad message.
