I have a few web sites running in IIS7 on Windows Server 2008 RC1 (I
think its RC1, build number is 6001). These websites are constantly
throwing the below error, and I cannot figure it out. Can anyone shed
some light on this?

Error: System.Runtime.InteropServices.COMException (0x800703E3): The I/
O operation has been aborted because of either a thread exit or an
application request. (Exception from HRESULT: 0x800703E3)

I've not seen this before. What is your application doing with COM? It may
help shed some light. Also, have a look at the eventvwr log to see if there
are further details.

The application does not use any COM objects. It only uses the .net
2.0 framework. It seems to me that IIS7 is using some COM objects
internally. My guess is that System.Web.Hosting.IIS7WorkerRequest
inherits System.Web.HttpWorkerRequest and ReadEntityCoreSync() is a
private method that is called by IIS7WorkerRequests implementation of
the ReadEntityBody() method. I think that it is a problem retrieving
the post variables from some underlying COM object. Notice the
"System.Web.HttpRequest.get_Form()" in the call stack. Here are some
links to how I got to this conclusion (I have been working on this
since after my first post):

http://msdn2.microsoft.com/en-us/lib...errequest.aspx
http://msdn2.microsoft.com/en-us/lib...ntitybody.aspx

Also, here is an error log entry:

Thanks for helping me out with this. Even a little nudge in the right

most likely the sender (browser) is closing the connection early (aborting
the post). if this happens a lot, a network trace may give a hint.

are you pages heavy (large viewstate)?

Thanks for the help Bruce. Its because of how often that it is
happening that I did not think that was the case. I will have to
verify that via a trace like you said. And yes, the pages are pretty
heavy. Viewstate is approaching 100KB (ick I know, we are cutting down
on this). The total HTML source is about 275KB. (Ugh that ratio is
horrible) But I'm confused as to how viewstate has an affect on this.
Are you talking client-side download/render time? Or is it something
else that a large viewstate can mess up?

Bruce,
I actually verified this pretty quickly by just testing and canceling
the post a couple of times. The error happened if I waited a bit then
canceled the post, much like a user would if they were sick of
waiting. The amount of these errors means that we are really ****ing
people off! I'm going to work on cutting down the viewstate
immediately.

A note to everyone: Do not use webcontrols for static content without
setting EnableViewState to false!

Alvin, thanks to you too. Now you have seen this before!

news:(E-Mail Removed)...
Bruce,
I actually verified this pretty quickly by just testing and canceling
the post a couple of times. The error happened if I waited a bit then
canceled the post, much like a user would if they were sick of
waiting. The amount of these errors means that we are really ****ing
people off! I'm going to work on cutting down the viewstate
immediately.

A note to everyone: Do not use webcontrols for static content without
setting EnableViewState to false!

Alvin, thanks to you too. Now you have seen this before!
