Why does aspx pages crash my machine?

Brett · Apr 15, 2005

I'm WinXP Pro. When I reference http://127.0.0.1/mysite/webform1.aspx
(newly created page in VS.NET), IE stalls then everything freezes. I can
click the title bar of applications but that is all. If I move beyond the
title bar, I get the hour glass. Nothing responsds except the mouse. I
have to turn the machine off at this point.

Running .NET 1.1. I can't find any one that knows why this happens. Any
suggestions?

Thanks,
Brett

I'll take a stab at it. You need to re-install visual studio.net. I think
you know that, you probably wanted someone to say it :-)

Why if VS.NET isn't running and I reference the URL in IE, everything still
crashes? Also, VS.NET runs with no problems. aspx is rendered by .NET
right? Why would that have anything to do with VS.NET?

in that case your IIS may be hosed. it's one or the other. IE provides a
stack dump when the critical crash occurs. Sift the stack and examine the
offending dll. The dll will be hosted by a process on your machine. It's
that process that is bugging out.

When this happens, there's no sifting through anything. Hard boot - that's
the only feature available.

sounds like an infinite loop.

What code is on that page. If you are doing a response.redirect to the same
page, your browser will enter an infinite loop with the web server on 301
messages and your browser (and probably your TCP stack) will lock down
tight.

Post code.

Have you tried another aspx page? Could it be an endless loop?

I've also uninstalled IIS and VS.NET. That obvisouly didn't help. I tried
running the above page again and it froze everything. It does run on
another XP machine.

Nothing about the crash in event viewer.

This is in WebForm1.aspx.vb:

Nothing bad there... Maybe it's an undocumented feature?

Other than Apache, I can't suggest anything else - sounds like something
rather fundamental is broken!!

I thought maybe stepping through with breakpoint would help. I can't do
that in an aspx page. Why doesn't WebForm1.aspx.vb show up in my project?
I've tried to add it but it still will not show up.

Thanks,

I can open the WebForm1.aspx page all day long in Firefox, with or without
the project open in VS.NET. I do notice the image doesn't show. So I
referenced it in the URL. Got a 404. Looking in IIS, I see only the bin
and _vti_cnf folders are available. That's why anything referencing the
images folder isn't showing. Maybe IE can't handle that and decides to
crash everything. Not sure.

How do I add another yellow (non virtual) folder in IIS under the website,
just like the two that are there? I only have options to add a virtual
folder or web extensions. I will add a folder for images and see what
happens.

I don't want to remove the images ref and try it in IE because I'm afraid it
will still crash everything. I do need the image folder ref in IIS though.

Brett

Danny T · Apr 16, 2005

Right-click on the .aspx page and choose "View Code"

Maybe IE can't handle that and decides to crash everything. Not sure.

Never seen IE crash over a broken image!

If you open Task Manager and sort by CPU usage, Does any process jump to
100% when it crashes?

The non-virtual folders in this list are physical folders in the
directory. If you right click on the Web Site and choose Browse (or
Open!), one of them should open the location on disk your website points
to, and the folder needs to be in there. If it's already there in Visual
Studio though, I can't imagine it not being there - sounds like IIS is
screwed?

I can't access it. The only thing available is the mouse. It always ends
with me hard booting.

What do you mean when you say it's there in VS.NET? I don't see folders in
VS.NET under my project. Only files.

Open it and set it to "always on top" before trying to access the page.
It might not redraw the screen to show anything useful, but you might
see iexplore of dllhost shoot up to 100%!

Ah, sorry, I thought you had a second folder not showing up. If you
right-click on your project, you can choose "New Folder". You could also
do that by browsing to C:\Inetpub\wwwroot yourself. These should then
show up in IIS.

OK. Nothing went to 100%. Everything stayed at 1 and 2% the whole time. I
was able to click stop on IE and the title bar said page cannot be displayed
but the main area remained white. At that point everything except task
manager stopped responding. I couldn't click the taskbar either. Nothing
in Task manager went above 10% usage. A few seconds later, task manager
stopped responding.

I click the power button on my laptop which brought up the log off, restart,
shut down options. I choose shut down. After 15 minutes, the computer did
shut down. During that time, I had popups to end task these in this order:
sgtray.exe
devenv.exe
iexplorer.exe
ctfmon.exe
explorer.exe (only the desktop background showed after this)
Windows Task Manager

It took another 5 minutes for the Windows logging off and shutting down
screen to go away.

do that by browsing to C:\Inetpub\wwwroot yourself. These should then show

I see all the folders in IIS now. The website I thought was being browsed
was actually outside of the wwwroot. ASP.NET browses in the wwwroot. I
added the folder I wanted ("images") and was able to then browse it.

Is there some other tool that can help with this problem?

Nick Malik [Microsoft] · Apr 17, 2005

I don't normally suggest this, but in your case, it's a real possibility:
Run an anti-spyware program like Spybot Search and Destroy and see if you
aren't getting hosed by a bug in a spyware app. Its what it sounds like to
me. I had this happen on one of my home systems. Spyware sometimes freaks
out when you access local host, especially using IP addresses.
