I'm a novice when it comes to such things, but hopefully I didn't butcher the basic point too much. I'm sure someone more knowledgeable will respond and set me straight. :)
Otherwise, you're right, it's odd behaviour to see in the logs. You're not blocking AOL or its IP ranges in your robots.txt file or htaccess (on Apache servers) file, are you? That one hit could be to your robots.txt file, and if it respects your robots.txt that'd be the last you see of that crawler.
Just a thought.
You'd put the robots.txt in your web root, which in your case would be in the public_html folder. You can have multiple robots.txt files.
There's a lot of helpful info here on WebmasterWorld about setting up a good robots.txt file [google.com].
