Hello again

Clearly the 4096-byte-truncation problem has been fixed.  Many thanks for
that.

But there's another problem, which I think I saw a few times last week and
which now seems fairly persistent, on some subset of the pages.

For example, when I try to access

   http://dbpedia.org/resource/Ottawa

or

   http://dbpedia.org/resource/Tetris

I get the following error from Apache (apologies for any messy
line-wrapping):

HttpException: HttpException: 500 SPARQL Request Failed: rethrew:

  javax.servlet.http.HttpServlet.service(HttpServlet.java:802)


I have no insight into which pages are subject to this error; I've just
found a few by chance.  If the server is behaving the same for everyone,
please bear in mind that the Tetris page is one of the examples offered at
http://wiki.dbpedia.org/OnlineAccess  :-)

Bye for now
