  Problem with ApplicationPools Reply Contact Hi,   Lately (for the last 4-6 days) I have started experiencing problem with my websites running on IIS7.  My websites running on Application Pools based on .net 2.0 (integrated and/or classic mode) seem to get 'stuck'. They will load all other pages properly but the page that gets 'stuck' all the links on that page stop responding. For example, if I clear spam comments in WordPress 2.7 based blog, the first bulk deletion works properly, the second bulk deletion just reloads the previous poage without performing any action. This also happens in .Net based Applications hosted on the same server. Recycling the pool solves the problem, but another change in the apps and the application pool has to be recycled again. I created new application pool and same thing happens with it. Server has these specs: Windos Server 2008 Enterprise, MSSQL 2k, MSSQL 2k5, MySQL5, PHP, .NET 1.1, .NET 2.0, Perl. Any ideas what might be going wrong? Regards, Fadi

Why don't you set FRT to timeout trigger when a request takes longer than say 30 seconds. If that doesn't trigger a log file the request probably never arrives in IIS.   Thomas Deml Program Manager Internet Information Services Microsoft Corp.

  Re: Problem with ApplicationPools Reply Contact  Well, I think i couldnt get my point across... The page "loads" but its not the desired one. Its like this (this is just one example of wordpress, other .NET applications like DNN also suffer from same problem) 1. I goto "Comments" -> "Spam" 2. select all the spam messages and use the 'Bulk Action' -> "Delete" 3. the comments are deleted and a message "xx comments deleted successfully" appears at the top. 4. I click on "Comments" -> "Pending" (legitimate comments I want to approve for example) 5. Page "loads" as if it was a normal load but I am still on the spam page with message "xx comments deleted successfull" at the top. No matter where I want to go within this edit-comments.php I get this page. 6. If i try to goto the WordPress Dashboard, it loads normally. 7. I goto "Comments" again and the spam page with "xx comments deleted successfully" keeps appearing. 8. Either if I wait for sometime or recycle the Application Pool and then go to this page, the problem is solved.  The twist is that this doesnt happen every time !! I still enabled FRT for time-taken = 30 secs and no log file generated. (Maybe because the page gets loaded within 30 seconds... its just that its out of the cache or something ??)

  Re: Problem with ApplicationPools Reply Contact fadi89: And if it is not IIS7 / AppPool related, then why it gets solved when AppPool is recycled ?   This could very easily be an application issue. When you recycle a app pool you basically reset afresh so in that state the app will work fine again. If the app is causing a problem then you have to recycle it is all fine again until the app leak memory, etc, etc. How is it loading up wrong pages? Separate files or pages as part of a query string asp or .NET? If it is displayed is based on code then I am sure how it can be an IIS issue. Most likely it is the application. I haven't used it but I imagine WordPress is now complex application (almost like middleware) and could be bugged in the way your WordPress and its configuration interfaces with IIS 7 configuration? So this is an app support issue. http://www.iisportal.com
