If you're upgrading to CF7, many of the issues will go away for free. On CF5 and below, you had to use CFLOCK to prevent memory corruption and avoid race conditions. On CFMX (6 and up), the underlying Java runtime takes care of the memory corruption for you, so CFLOCK is only needed for avoiding race conditions.
I'd do the upgrade first, and then if you're still having issues, worry about going back and adding CFLOCK all over the place. CFLOCK is a performance hog (because it reduces the ability of CF to run multiple requests concurrently), and should be avoided where possible. I suspect most of the places you'd be adding it will be unneeded on CF7. cheers, barneyb On 11/7/05, Horne, Jeff <[EMAIL PROTECTED]> wrote: > We have recently discovered that many of the variables on our site are not > enclosed by cflock tags.
