From: steve on 2 Aug 2007 20:55 Hi, We are running an ASP application in IIS6. This site used to run perfectly but over the last year we have been having increasing problems especially since we upgraded from II5 to IIS6 I think. Symptoms: ...Connection_Dropped DefaultAppPool a lot for lots of pages ...System gets slower and slower ...Soft Artisans File up COM object crashes and reports that is can't be created in the ASP page All of the above issues are fixed instantly once IIS is restarted and then it slowly gets worse until we have to do it again. The COM issue once it starts continues EVERY time until IIS is restarted. I have looked around and it seems to be said that IIS6 shouldn't need to be restarted and should recycle the application pool or something. This app will eventually get rewritten in .NET but that is more a long term solution not an immediate one and we need to fix this now. Would having a batch job restarting IIS every night help or be possible? I have attached more info below which states the the asp.dll is unhealthy. Any ideas would be greatfully received. Cheers, Steve steve(a)dangerfield.biz ISAPI 'C:\WINDOWS\system32\inetsrv\asp.dll' reported itself as unhealthy for the following reason: 'ASP unhealthy because 100% of executing requests are hung and 1% of the request queue is full.'.
