That's a sample of what's showing up on an average of about once every two seconds, since May 31st. Notables, other than the constant site pull (direct from the cgi, not the XML feed) are that it's a feed aggregator (a client), running on a Linux box, and the IP is an address in Hanoi, South Korea.
Research on the IP shows that it belongs to the Corporation for Financing and Promoting Technology, AKA FPT Communications, FPT Telecom and FPT Corp. Google has about 681 matches for that exact string, with a ton of other matches for the Corp's subsidiaries and aliases. In short, one of its functions is it's the local ISP and, apparently, one of their users has a misconfigured feed aggregator.
So, if you're in South Korea and you've been using a Linux-based feed aggregator called Liferea for about 2 months now, please check your configuration. This site only changes about once per day and there is no need for the constant checking. Might I suggest an intermediate feed aggregator, such as Bloglines? If you're interested, here is a list of the feeds that I subscribe to (hint: there's an "Export Subscriptions" button at the bottom of the page, if you want the OPML version).
Just please stop pounding on the site.
