Friends,
We are preparing for Beta release of a new ASP.NET project, but our initial
in-house tests are not going well. We have had W3WP.exe (and aspnet_wp.exe)
die, and we feel we can monitor it's death and sometimes get useful
information out of the DMP file.
But lately, W3WP.exe lives, but appears hung. New request to the
application hang unresponsive, existing user sessions are unresponsive, and
eventually session timeout and go away. W3WP.exe had grown to around 250mb,
but we have a full 2gb on the test server, so doubt this is a memory thing.
Recycling that App Pool starts a new W3WP.exe, and folks can login to our
app and begin again. The "hung" W3WP.exe lives until we kill it.
I don't know were to begin. Has anybody seen W3WP.exe stop serving things?
How might we proceed? (Debugging doesn't seem possible since we need a real
server load to get this situation to occur.)
Any thoughts, words, or links will be very much appreciated! Thanks in
advance.

Give brief description about what operations your web application is
supposed to perform, than someone might be able to help you guess what's
going wrong. (e.g.: Whether accept upload files, control hardware, use other
3rd party COM objects, etc.)

We query a DB using our own API, display records in a grid, allow add and
update, etc. Mostly Web Form stuff. The bottom line is that the worker
process stop responding, CPU use that process is zero, and I don't knwo how
to even begin to track this down.

Is your W3WP.EXE really stop responding? You can try adding an ASPX page
with one literal control that on the Page_Load of code-behind will output
some server-side value like the current username or a value in Session
variables.
When the w3wp.exe appears hang, try browse that page. If it can successfully
display, then the w3wp.exe is not hang, just for some reason cannot display
your page correctly.
Concerning memory problem, seems your web application will store data in
memory until your session timeouts and GC recollected the space. Actually if
I were you, I'll try to use DataReader to read data and write my own routine
to "draw" the table myself, so I can free the datareader once I finish
rendering the table, but then it'll be less productive... you'll decide
yourself whether you have time to try this out and see if there's any
difference... (I think this may not be the best way to do this, you can also
wait to see if others have other inputs)

Hi All,
I'm using w2k3 and IIS6, is it true that when I start
the .net web application, there will be a process
w3wp.exe? As my application is using asp.net, but when I
start the web site, there is no w3wp.exe in task
manager. And a process that related to this web
application always stop suddenly. Could anyone help?
Thank you.

I'm developing a web site with asp.net, mainly vb on a Windows 2003 server.
Quite often the web site stops responding for 15-20 seconds.
A web page that usually take 2 seconds to produce takes forever.
During this time,the w3wp process takes 100% of the CPU time.
I'm using only asp.net, no extra stuff like Commerce server or anything.
Please? Any clues or help would be much appreciated!

Hi everybody!
I have a really big problem with ASP.NET application. I noticed that the

it raise a certain value, w3wp crashes and restart just after. My

So I have to resolve 2 problem :
-Why the memory size of the w3wp increase non stop.
- Why the w3wp crashes (in the case where there is no link between those

I have unchecked all options in IIS6 application pool,
so I assume no worker process recycling will be performed whether any event
occured.
what will be happened when w3wp.exe used memory exceed physical memory.

We make an ASP.NET web application and we host it for our customers. We

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
