java运行方法栈溢出

最近系统出现些奇怪的问题，抛出信息如下：

很久没攻技术难点了，很是兴奋，就开始对此问题进行了解，观察下发现，有以下规律出现：

1、虽然方法栈溢出，但服务器还可以正常运行，并没有宕机。

2、目前部分时候可以出现此问题。

 

最后，试探性的考虑了下，是否觉得方法栈空间不够；所以在启动时，加大方法栈空间，参数为-Xss512k，重新启动后，问题得到解决。

不过也很奇怪通常情况下，栈空间的默认值是够用的，以后还需要对代码进行更深入的研究。

 

 

这几天，测试下来发现问题没有想象的那么简单，因为通过多次测试后发现，在增加栈空间后，还是会抛出这个错误，暂没查出原因，我将继续关注……

 

 

找出问题所在。
