Some quick thoughts, what is the timeout value for your session variables?
And are these customers exceeding that amount of time when the error occurs?
Are you <cflock>ing your reads and writes with regards to your session
variables?

Subject: Runtime session var error.
Hi all,
I have a really annoying intermittent problem out on a customer's live site
where they submit a form and they get an error that says that a session var
is nonexistent. This is a real pain because I can't reproduce the problem
on either the customer's website or my development box. Only some of the
customer's users have a problem , I checked the DB and saw that a good
number of people have submitted without problems.
I had an issue last night where session vars were lost because the CF cookie
wasn't written because I had done some CFLOCATION's in the login handler
page which was also the very first of the app. I replaced all of these with
JavaScript redirects and it worked fine.
This login page directs the user to a survey form which then posts to an
action page.
The action page is the page that reports non-existent session vars. I know
that the survey form can get at the session vars because I use some as
hidden vars.
Only one application.cfm page, and there are no cflocation tags on the form
page.
I've configured an error handler to email me details for any error on the
action page.
I've modifed the error handler to send me a dump of all form and session
vars the next time an error occurs.
Any ideas? The customer is about to have a hemorrhage.
Thanks a million Kev
