Pwnna's answer have good concept, bud doesn't work for me. Here is solution that work's for me:

fit_modal_body = function (modal, padding) {
    var windowHeight = $(window).height();
    var modalHeight = modal.height();

    var dif = windowHeight - (modalHeight + 2*padding);
    var modalBody = $(".modal-body:first", modal);
    modalBody.css("max-height", modalBody.height() + dif);
};

resizeLastWindow = function () {
    fit_modal_body($(".modal-dialog:last"), 15);
};

$(window).resize(resizeLastWindow);

It's depend's on css:

.modal-body {
    overflow-y: auto; 
}
