RuntimeError: can't start new thread

[xingstarx]

NotImplementedError: That compression method is not supported

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/xingxing/pythonProjects/ZipCracker/ZipCracker.py", line 161, in <module>
    t.start()

感谢大佬的开源项目，有个问题想要咨询下呢，我运行这个项目来破解一个zip文件，报错了。 崩溃日志如上，感觉是线程数开启太多了，爆炸了，大佬能给点指点么。
