I am doing a logistics in my hand, I have a quick end; but the recent problem is a headache; the first problem is that session is too late, the processing method is to change the MODE category into StateServer, then enable ASP sessionState Server service . Thus so, Session premature The loss problem is solved, but found that W3WP.exe is crazy to eat resources at the same time, and the CPU has 90%, the memory is 400M, and the web program is automatically hanging, it is definitely not normal. Server configuration is a dedicated server: CPU: P42.8G, memory: 1G, system Windows2003, running programs are: Oracle9i, SQL Server, Web logistics system, there is an OA. Workaround: 1. I doubt it is a web.config page. Debug = true causes automatic modulation, set to debug = false, or fail. 2. I thought it was the reason for the ASP sessionState Server service because did not enable this service in the previous project, and did not have a serious CPU and memory, and the ASP sessionState Server was stopped. Web.config recovered to Original, then set IIS> Select Current Projects> Properties> Virtual Directory> Configuration> Options> Session Time: 120 minutes, then discover still the situation of raging resources, but it is better than before. 3. Doubt is too much system running program, and it is a large number of resources, may have to move to another server, do not know how to solve it; if any of my encounters, I welcome this situation. !
