Hi Alex, Thank you. I'll try to provide as much info as I can. I currently run about 12 websites on the server. None of them use CFCs though and even the sessions stored are just email and username. Also, I don't conduct XMLSearch.
I would love to share more info. What info is pertinent and how can I retrieve these info? From the Tomcat Logs?
