Application Hangs .. HELP

Not sure what my problem might be - I suspect it's something related to IIS though.

I have 2 web applications on a server. 1 is the main application that accesses a couple of databases and gets user input. The 2nd app is just a single page that displays a label for testing purposes.

Every once in a while it seems that the main application stops working. I open up internet explorer and enter in my URL and nothing happens but a blank white page with the globe spinning and spinning forever. No logs anywhere saying anything is wrong (that I can see).

My 2nd test application does the same thing - so I know it's not anything database related.

I have no problems running this on my own development PC or on the test server.

When I have the problem on the production server, my only choice is to go into Internet Services Manager and re-start IIS. That usually fixes the problem, although not always.

Has anybody seen this problem and fixed it or know where I should start to look? Thanks a bunch!!
 
Hi Vince,

I have the same problem. My application works fine on staging servers
(tried various in-house servers, no problems), but eventually
locks up on the web server online. We are certain it is some sort of
setting on IIS on the web server, but tried every conceivable setting on
this machine and, still the app locks up after anywhere from 20 to 100 page
loads. Server logs do not indicate any problems whatsoever. ASP
applications run just fine. Whatever it is, it appears that database
connections are opened, but never closed (only on the production webserver).
We poured over the code and cannot find anything wrong. We ruled out the
SQL server as we can run the app locally with a connection to the remote SQL
server without crashing.
Reinstalling the Framework (1.1) did not work, recreating a site in IIS does
not work.
We are running IIS 5.5 (Win2K server - all the latest hotfixes, SPs etc) on
a Dell Dual Xeon P4 1.3Ghz blade.
All 3rd party apps (for the ASP apps) are running identically on the
in-house servers (also Dells dual proc).
I am worried that rebuilding the server (a 2 week process incidentally) will
not fix the problem and maybe there is an unresolved bug in the FW. My only
guess is that a file somewhere in the system is corrupt or maybe another
copy of a dll is located elsewhere on the system. This could take an
eternity to determine or find! With no error messages to go on, this is
truly a shot in the dark!
All I can say is good luck!

Dave

Kind of glad to know that I'm not the only one with this problem, just wish someone would post a solution to it.
 
I am looking for a solution to a similar problem. We recently upgraded our server to Windows 2003 and IIS6. Now our production web site will periodically stop responding. The only way we have found to get it respond is to restart the Web Publishing service (we used to restart IIS but found that the web publishing service was sufficient).

We have isolated the problem to ASP pages. When the site fails to respond we have tried other pages within the site to see what exactly we could find. We found that HTM pages were being returned correctly and would continue to display. ASP pages however would fail to respond. I suspect ASP.DLL is causing some kind of problem.

We are looking for any clues to help fix this problem or a workaround so our site doesn't hang so frequently (once a day or more).

Andy
