I have an error java.lang.IllegalStateException: Could not find child entry in parent;

At the moment I'm doing an insert in access through the connection with ucanaccess, the connection works but the query gets me some exceptions, with some users when I insert them and this is what I get in the console:

  

java.lang.IllegalStateException: Could not find child entry in parent;   childEntry NodeEntry [rowId = 400691: 2, subPage = 398333, bytes = (14) 7F 80 00   0B E8 7F C0 E4 F4 47 A2 B3 C4 D6]; parent NodeDataPage [318587]   56830, 10326,   (299665) [entries = [NodeEntry [rowId = 8497: 31, subPage = 57319, bytes = (14) 7F   80 00 0A 31 7F C0 E4 86 DA 9D 33 F5   61], NodeEntry [rowId = 228496: 40, subPage = 10286, bytes = (14) 7F 80 00 0A 31   7F C0 E4 90 67 F9 14 19

     

net.ucanaccess.jdbc.UcanaccessSQLException: Could not find child entry   in parent;

Does anyone know anything about that error that comes to me?

This is the manager where I call the connection and send it to the DAO

public boolean RegistroSalida(String id)throws Exception{
    connection = ConexionAccess.getConexion();
    boolean respuesta = false;
    try {
        objDAO = new LectorDAO();
        respuesta = objDAO.RegistroSalida(id,connection);
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println(e);
    }
    //connection.close();
    return respuesta;
}

here is where I do the insert that I do in the DAO

public boolean RegistroSalida(String id, Connection conexion) throws Exception{
        boolean respuesta = false;
        try {
            String query = "INSERT INTO checkinout (USERID,CHECKTIME,CHECKTYPE,VERIFYCODE,SENSORID,Memoinfo,WorkCode,sn,UserExtFmt) "
                    + " SELECT USERINFO.USERID, now(), 'I', 3, '107', '', 0 , '' , 1 "
                    + " FROM USERINFO" + " WHERE (((USERINFO.[SSN])='"+ id +"'));";

            PreparedStatement ps = conexion.prepareStatement(query);
            System.out.println(query);
            if (ps.executeUpdate() >= 0)
                respuesta = true;
                System.out.println("oK");

        } catch (Exception e) {
            e.printStackTrace();
            System.out.println(e);
            System.out.println("Paila");
        }
        return respuesta;
    }

This is the connection to the Access database:

public class ConexionAccess {     private static Connection cn = null;

public static Connection getConexion() throws SQLException {
    try {
        Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
        cn = DriverManager.getConnection("jdbc:ucanaccess://D:/attBackup01042015.mdb;memory=true");
    } catch (Exception e) {
        e.printStackTrace();
    }
    return cn;
}

}
