Hi,

First, the symptoms: I was doing some tests on sites with many PDFs, and
the Fetcher was gradually slowing down, until it became stuck. This was
repeatable. A thread dump showed all threads waiting somewhere in PDFBox
code (which is used by parse-pdf). In an email exchange with the author
(Ben Litchfield) he confirmed that there was a problem in the latest
official release of PDFBox, which could result in such behaviour.

If you experienced such problems, the fix is to use the latest CVS
version of PDFBox, where this problem is believed to be fixed.
