ASP.NET Timeout Issues

I'm working on a legacy system that has the following timeout values in web.config. 

<sessionState timeout="120" />
...
<forms name="login" timeout="240" />

I also have the following implemented to prevent Null session variable issues. Here's the generic version: 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    If Not IsPostBack Then
        Session("DocNum") = ""
    Else
        If Session("DocNum") Is Nothing Then
            Response.Redirect("~/index.aspx?e=SessionExpired")
        End If
    End If

End Sub

It appears that the session variable is being cleared well under 120 min setting even though many users are on the system. This seems to be happening regularly.

I've read that the application pool could be causing this but how so? What other configurations and time-out values might be causing this issue?

Thanks for the help.

If your session state is set to InProc, the recycle settings for the application pool could be resetting the App Pool which clears session. "InProc" means that session is stored in memory, and as a result, any application pool resets would lose what is stored in session. You can check the system event log of the web server to see if there are any events for the application pool recycling due to a regular, recycling schedule or an error.
