多谢！

问题是这个脚本在其他机子（相同配置）上运行是没有问题的。不同的是出问题的机子上有另外的python程序在运行。

多个python程序运行时会相互干扰么（在 recursion depth 上 ）？

还是程序本身的问题吧，debug

递归调用太多层了。要么改代码，避免这样的递归。要么改递归调用的上限。

看这里：

http://docs.python.org/library/sys.html#sys.getrecursionlimit 和这里： http://docs.python.org/library/sys.html#sys.setrecursionlimit

唉，死循环了。
