Kryoが設定したキャッシュ領域が小さすぎるため
データをシーケンス化して書く場合:

    Output output = new Output(128, 10240);
    kryo.writeClassAndObject(output, obj);

OutPutのコンストラクタを見て

    public Output (int bufferSize, int maxBufferSize) {
        if (maxBufferSize < -1) throw new IllegalArgumentException("maxBufferSize cannot be < -1: " + maxBufferSize);
        this.capacity = bufferSize;
        this.maxCapacity = maxBufferSize == -1 ? Integer.MAX_VALUE : maxBufferSize;
        buffer = new byte[bufferSize];
    }

ここで設定したbufferの初期サイズと最大値を知っています.私のところで設定した最大は10240 byte、つまり10 kです.
だからここでbufferサイズを調整すればいいです.
