I get a problem from time to time which I think is down to the RSS feed aggregator XHLD. The module is great and does everything I wnat it to, but now and again it lets me down.

The Front Page has an xhld block showing the 15 latest feeds, and has a cache time of 5 minutes. Now and again the front page takes ages to load, or gives a white page, even whilst all the other pages of the website work. I suspect that a problem with one of the feeds is causing this, but I am not sure. How ccan I check?

The problem always disappears after a while all on it own.
