I actually posted my review on my blog:
http://www.scriptedlizard.com/thevault/carbonite-online-backup-trial-review
The Carbonite CEO posted. I was a bit skeptical, but I emailed him directly, and indeed he did post the comment. They extended my trial by 30 days, and had me email my logs to them. I did a clean install tonight of the OS and after installing Wallet, will install Carbonite and watch it closely. I will then start installing my other apps and try to see which app it is.
They also told me to lower priority, and just pause, which is unacceptable. Then they said my MobileMe was causing it to act up, and to disable that... um.... no. They said that they only had 3 reports of this issue, which I don't buy. I've seen more than that in posts on the web.
I'll post back my results.
