TOracleConnection - memory rising with instant client 19.8

[vertnik]

Hello!

I found memory problem when using TOracleConnection with Instant Client 19.8.
Bellow is the code from my application. Every time the connection is closed and
opened again, the memory used by application is rising.

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  OracleConnection1.Close(True);
  OracleConnection1.Open;
end;         

Just to mention, I do not have problems with older version of instant client 12.

Thanks in advance,
Robert
