A session is lost after a click of a button!

I am saving my typed dataset to a session:
Session.Add("ds_FPInfo_Group", Dataset11)

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

'\\To retrieve the session variable'\\
If Page.IsPostBack Then
Dataset11 = CType(Session("ds_FPInfo_Group"),
Data.DataSet)
endif
end sub
The retrieve works well, but when I click on a cmdSave button, the
session is lost.
I have asked other developers in my group and we can not find the answer.
Appreciate your help!!

session is typically lost when the application pool recycles. have a look at
your event logs first to see if that is the reason.

This application test is stored in my local machine running xp Professional
and IIS5
I see the dataset populated after postback and at the command button the
dataset is null. It supposed to be in memory.

it case you didn't catch my drift, run eventvwr at the command prompt and
have a look at the application logs for any application recycled message
errors that may appear.

Can you be more specific about the application pool? Where, exactly, can we find the logs for the pool? I've looked (I think) in all the usual places, but am finding nothing.

Our application is suffering from (apparently) the same problem. If there is any kind of load on the server, beside the app itself, people get booted out of the app. I think I've narrowed it down to the loss of session info.

Any more thoughts?

run inetmgr from the command prompt expand default websites, application
pool will be there. This is only for IIS 6 on server 03.

run eventwr on the command prompt, examine the application logs for
application pool recylced messages. correlate the time with the problems you
are seeing.
