Java 如何跟踪和防止在不同进程中运行的c3po中出现死锁？

我有一个非常简单的计算，它产生字母矩阵，可能找到矩阵中的所有单词。单词中的字母是相邻的单元格

   for (int i = 0; i < 500; i++) {
        System.out.println(i);
        Matrix matrix = new Matrix(4);
        matrix.scanWordsRandomly(9);
        matrix.printMatrix();
        System.out.println(matrix.getSollSize());
        matrix.write_to_db();
    }

我遇到了如下僵局：
