【求助】使用RFT在IE上进行自动化测试，出现IE异常终止。请问有什么办法可以解决

genglz

使用RFT在IE上进行自动化测试时，运行几个用例会随机出现IE异常终止，并且在桌面上会留下java虚拟机的异常日志。
RFT版本为6.1，对页面控件的使用全是通过find方法，并且在使用结束后用注销掉了。

请问可能有哪些因素引发的该问题，有什么方法可以解决。谢谢！
由于不能贴附件，粘贴部分异常日志如下：

这是因为内存占用过高导致，我的也是，以前总是IE自动关闭，大概是因为用的静态变量或方法太多了，一直保存在内存中，导致内存占用率持续过高。后来我把静态变量或静态方法改写为非静态的，这种情况就改善了许多，你不妨试试看
