Regarding the timeout value not being specifically set (within the
application.cfm) should be fine as the server to use what is defined in the
Admin section (20 mins I believe). Again though, I don't know if this may
be part of the cause if the customer(s) with the problem were actually
'inactive' for that amount of time. But if so, you would think that any
other session vars you have set would be 'timed out' as well.
As far as session vars overwriting themselves, you don't have to be in a
framed environment for this to happen. I've read through way to many
threads on Allaire's site regarding session variables coming up as missing
or overwritten. The bottom line on that one, any time you read or
write/update a session, (server or application) variable, lock it.
Possibly sharing (even pieces) of the code might help someone on CF-Talk, to
include myself, with resolving this problem.

Subject: Re: Runtime session var error.
Timeout wasn't specifically set, set it to an hour now.
I have locks around each session var modification.
This doesn't even have any frames so it'd be surprising if session vars were
overwriting each other anyway right?
What's strange is that the error description to me was that a user tried to
submit, encountered an error (the error catcher at the time redirected them
to the login page).
They maintain that even when they logged in again abd submitted
straightaway, they came across the error again. This smacks of a
programmatic error but I can't reproduce the problem, I've blown away
cookies, used different browsers and logged in as different users to no
avail.
