I have an application used for Survey. I have stored the survey question in cash(server). The problem i am facing is that sometimes something happens to cash and it is empty and the application errors. This expiring of cash is not continues it happens any time sometime it will not happen for days and sometime it happens every time. The application is hosted on 2 server with round robin load balancing. I have tried to set the expire time to Max and priority ti high. For work around I am checking for Cash in every click and if empty re- populating the cash.IIS is 6.1Windows 2003 server.net 2.0
