ColdFusion hanging

Question

Hi,
I have a ColdFusion 8 application that connects to a MySQL 5.1 database.  Client variables are stored in the database.  Every so often (once every few days or so), one of our users will experience a hanging issue, usually triggered by the user attempting to log in and start a new session.  And once the user triggers this hanging issue, all other pages (session or non-session pages) experience this hang, even if called under another browser session.  I'm wondering if this is a session issue or something to do with the cfapplication tag?
This seems to happen with users using MSIE as their browser, although I can't be certain this is always the case.  I should also note that the login section of our site starts a secure (SSL) session, although I'm not sure if this has anything to do with the hanging issue.
Finally, I should note that my application is hosted on a shared server.  I don't believe that shared traffic is the issue here though because in troubleshooting this issue with my hosting company, they actually moved my site to a dedicated server and we still experienced the hanging issue periodically.
I've been troubleshooting this issue with my hosting company for almost two months now with no fix.  I've searched all the forums and although I've seen other posts regarding ColdFusion hanging (mostly in MX), they do not seem to address the same issue I'm having.
Has anyone else experienced this problem and found a fix?
Thanks,
Tony

Yes, here is code from my login page that starts the user's session:
<cfquery name="GetUser" datasource="SiteDB" maxrows="1">
select * from USERS
where USERNAME = '#Username#' and PASSWORD = '#Password#'
</cfquery>
<cfif isDefined("Client.User_ID")>
<cfset Deleted = DeleteClientVariable("User_ID")>
</cfif>
<cfapplication name="UserSession"
clientmanagement="Yes"
clientstorage="SiteDB"
setclientcookies="Yes"
sessionmanagement="Yes"
sessiontimeout="#createTimeSpan(1,0,30,0)#"
applicationtimeout="#createTimeSpan(1,0,30,0)#"
setdomaincookies="No">
<cfset Client.User_ID = #GetUser.ID#>
<cfcookie name="SiteUser" value="#GetUser.ID#" expires="Never">
<cfif isDefined("AutoLogin")>
<cfcookie name="SiteLogin" value="#GetUser.ID#" expires="Never">
</cfif>
And here is the code my my application.cfm file:
<cfapplication name="UserSession"
clientmanagement="Yes"
clientstorage="SiteDB"
setclientcookies="Yes"
sessionmanagement="Yes"
sessiontimeout="#createTimeSpan(1,0,30,0)#"
applicationtimeout="#createTimeSpan(1,0,30,0)#"
setdomaincookies="No">
<cfif isDefined("Client.User_ID")>
<cfquery name="GetUser" datasource="SiteDB" maxrows="1">
  select *
  from USERS
  where ID = #client.User_ID#
</cfquery>
<cfif GetUser.recordCount gt "0">
   <cfquery name="RecordUserHit" datasource="SiteDB">
    update USERS
    set HITCOUNT = HITCOUNT + 1,
     LASTHIT = #Now()#
    where ID = #client.User_ID#
   </cfquery>
<cfelse>
  <cfoutput>
   <script language="JavaScript">
    top.location.replace("../index.cfm");
   </script>
  </cfoutput>
  <cfabort>
</cfif>
<cfelse>
<cfoutput>
  <script language="JavaScript">
   top.location.replace("../index.cfm");
  </script>
</cfoutput>
<cfabort>
</cfif>
Thanks for your help.
