RE: Session Variables Suddenly Stopped Working

You may want to see if the CF Admin set strict locking validation otherwise;

I don't really see why you would throw that error off-hand (assuming you are on CF5?) however I would suggest some changes:

<cfapplication
name="solarcenter"
sessionmanagement="Yes"
clientmanagement="Yes"
applicationtimeout="#createTimespan(0,0,90,0)#"
sessiontimeout="#CreateTimespan(0,0,90,0)#">

Move the cfscript out of the application lock since you are dealing only with session variables and create a session lock around them

<cflock timeout="5" throwontimeout="no" type="readonly" scope="session">

<cfscript>
  sUserInfo = StructNew();
  sUserInfo.Address="#CGI.REMOTE_ADDR#";
  sUserInfo.CFID="#session.cfid#";
  sUserInfo.Token="#session.cftoken#";
  sUserInfo.Address="#CGI.REMOTE_ADDR#";
  sUserInfo.Time="#Now()#";
  sUserInfo.Template="#CGI.CF_Template_Path#";
  ID = "#session.cfid##session.cftoken#";
</cfscript>
</cflock>

Try changing from using the variable name #APPLICATION.applicationName# to just the hardcoded name solarcenter and reduce the timeout value:

<cflock name="solarcenter" type="Exclusive" timeout="5" throwontimeout="Yes">

<cfparam name="APPLICATION.SessionTracker" default=#StructNew()#>
<cfset dummy = StructInsert(APPLICATION.SessionTracker, ID, sUserInfo, true)>
</cflock>

Of course there is always the 'When in doubt - stop/start the CF service' :-)

I played with some of the error handling and was able to get a little more
information.

The message says "Application.applicationName is in a scope that contains
data shared across threads and cannot be accessed without an active lock".

I know very little about session variables and locking.  Does that mean the
problem is with the lock itself?
