Sorry for a "me too" posting. I'd like to add that the result of the test suite is extremely flaky on my linux box. When I run the test a dozen times, I sometimes get 100% OK and most of the time some random test fails. I can see no pattern. The perls I used were bleadperl and maintperl current state of affairs and stock 5.8.8.

The test suite just passed. Sunspots?

I'd say this is the same bug that I reported to H:S:S yesterday: http://rt.cpan.org/Ticket/Display.html?id=28122 So Andy, if you can throttle your CPU, give it a try, maybe you can reproduce a few failing tests. My current statistics on T:W:M 1.14 is PASS 80 : FAIL 29 Thanks,

For the record, we're seeing this on Debian too: http://bugs.debian.org/439470 As I wrote in CPAN #28122, I think the fundamental problem is that HTTP::Server::Simple::background() returns before the server is ready to answer requests. I'm attaching a proposed workaround for test link_content.t in Test::WWW::Mechanize: it always waits one second before issuing the GET request. There's also an additional test for better diagnostics, should the problem resurface. Cheers, -- Niko Tyni (Debian Perl Group) ntyni@iki.fi
