Why does the gatherer dump core?
Core dumps can occur for a variety of reasons. However – a number of people have reported core dumps occuring in the gatherer before any objects are fetched. This is most often caused by the site having a malformed robots.txt file. If you’re attempting to fetch a page http://www.blob.org/blobby/blah.html then Harvest will first check the robots.txt file at http://www.blob.org/robots.txt The correct format of this file is documented at http://info.webcrawler.com/mak/projects/robots/norobots-rfc.html Under some circumstances Harvest may dump core if this file is corrupt.
