Couple of things that might help you pinpoint the issue. 1. Do you have FusionReactor or SeeFusion Installed? If not, I would highly recommend a monitoring tool. We use FusionReactor and its the best 300$ investment we have done. You could try the trial version at least to see why you are having issues.
2. You mentioned, its Enterprise CF license. You can also try using CF built-in monitoring tool available for CFers since CF 8. Try those first and see if you can isolate the issue. CFDirectory was famous for issues in CF 7. I am not sure how it does in CF9. Look for permissions etc also. I remember one app of ours was using CFDirectory and the location of directory was wrong. This caused the page to hang up like crazy causing issues. One more thing. Check out the CF logs and run time logs. That will also give some insight about the problems you are having. Hope this helps. <Ajas Mohammed /> http://ajashadi.blogspot.com We cannot become what we need to be, remaining what we are. No matter what, find a way. Because thats what winners do. You can't improve what you don't measure. Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.
