1、【重点，优先处理】动态程序集：
A、建议对 Application_BeginRequest 中大量的 Regex 采用缓存策略
不需要对每个 Request 生成多个 Regex ，会造成服务器动态程序集过多，内存碎片超大
B、检查代码中是否存在手动调用 XmlSerialization 对象，
此对象也会动态生成程序集，解决方法见：http://support.microsoft.com/kb/886385/en-us
2、系统异常【详见随后文档中的详细附录】
3、其他问题：
A、系统中的部分数据连接未关闭，一直保持连接，请检查相关代码。
特别是 SqlConnection , SqlCommand, DataReader
B、系统多余使用 DataTable 并未得到及时的释放，导致内存占用过大
Total 243 DataTable objects
请先按照上述问题进行修改。
若IIS再次出现crash 情况，请到我的博客或CSDN资源中心下载工具，运行以监控IIS。
下载完成后，请查阅其“使用说明.txt”以了解其使用方法。
