Session time-out,when the page breaks?

Hi..

I had published a website in the server( I am using VS 2005,ASP.NET2.0, With C#) . I tried testing the site by asking several users to login to the website and do unit testing. At one instance of time, the page breaks for a particular user. When the page breaks, the other users who are tesing in their machine are getting a session time-out and are forced to log out.

Why is such a session-time out issue happening, when one of the users page breaks. I have set the session variable to 20 minutes,which is the default. But what's confusing is , when one of the user's page breaks, the others get a session time-out? Why is such a session-time out occuring?

Please help.

Thanks.

What do you mean when you say "the page breaks?" If an app pool cycles you might see this effect. Have you diagnosed the "page break" to see what happens?

Jeff

Thank you very much for the reply.

The page break, I referred is the page crashing(asp.net error page) .I have customized the error page to show, An Unexpected error occurred, please try after some time.

But when the user tries the same steps to find the page crash, he is not able to, as the page works well. This is a kind of absurd. The page is not crashing always, but it is random. I checked the log, but it was not providing much information. I also could not re-trace the page crash, as the page worked well.

But why is the session getting timed out for the other users, when one of the users page crashes?

Thanks.

Hi..

I am sorry that I forgot to include a scenario in my web page,which i am doing. I have written a code to delete a folder in the session end in global.asax. When i commented the code, and tried testing, the session time out was not occuring.

I searched in the google, and came out with this:

http://www.velocityreviews.com/forums/t116975-all-session-are-getting-down-when-i-delete-sessions-folders.html

Is this the reason for all sessions getting timed-out, when a page crashes?

Thanks

Hi Venkatzeus,

As far as i know, if you delete a folder which is in your application directory, the appDomain will restart, and you will lose your session.

I hope this helps.

This happens as your worker process memory limits get full and asp.net worker process gets restarted. how to do this setting you can find at

http://www.asp.net/faq/AspNetAndIIS6.aspx

But I think you needs to findout why its getting full.

When you get this error check server CPU Usage what it shows?

then debug.

HI,,

Thank you very much for the reply. I will try with it and provide the results.

Thanks

Session Timeout.

Friends,
We have a simple application which has login page, users login to it
and enter their contact details and all other stuff. It is working
fine. Now we have moved to new windows 2003 server. The page works
but it gets refreshed every 5 mintues and goes back to login.aspx page.
How do I fix this.
Thanks for any help.
KAdd this in your Web.config file to elongate Session to 60min for example:
<sessionState cookieless="UseCookies" mode="InProc" timeout="60" />
but add it between
<system.web> </system.web>

no that did not help. same thing is happening again.
Do you have code in your page to redirect to your login page? Sounds like
your session is timing out and your code is kicking in to repost. Write some
code in your session_end event handler to dump a file with a time-stamp to
tell you when the session is dying. You can trouble-shoot from there.

Hi Alvin,
thanks for the advise. Iam inputting the values to a text file when
session times out. It is coming as 60 seconds. So the session is
timing out at every 60 seconds, but I could not find where to change
these value. I checked the web.config and machine.config and
application pools .
Let me know specific place to change this value.
thanks,
K
So you have an override somewhere in your code because the timeout value is
20 minutes by default. Search your code for that value. Alternatively, it
may be overridden in the web.config file. As a quick test, you can set
session.timeout = 10 minutes. It should stick otherwise, you have something
funky going on in your app that you either don't know about or aren't
sharing.

Nothing in the code, nothing in the web.config. It has to be some
other place. I have seen all my code and no where I am setting these
values.
I tried changing session timeout to 10 minutes and still nothing
happens. So it got to be some where, not that simple.
Where else it can be.?
Thanks.
K
you need that check. go back and put it in there so that your application
can be resilient to memory issues. However, raise the limit to around 1gig
or so. The reason for this is that the application pool should be recycled
if an errant application (your code) decides to hog memory. Removing that
check prevents detection of this and other conditions.

Thanks for all your help. It got fixed just now. The problem is
Virtual memory was so low (250MB), so every time a worker process
initiates it goes to 250 MB and it recycles, so what we did was, we
just removed the check box next to virtual memory of application pool.
that's it. It works...great relief.
Thanks,
K
Where is the Virtual memory checked/set? Somewhere in IIS?
