Hi Leif, It's HTTP, no HTTPS.
http://bne-b-ccs1.cdn.aarnet.edu.au/pub/ubuntu/archive/dists/saucy/main/binary-i386/Packages.bz2 is a URL I've been using to test it. A simple while true loop will bring it up, after a few requests. I used the following configure line to setup the software. ./configure --prefix=/srv/trafficserver-4.1.2 --sysconfdir=/srv/trafficserver-4.1.2/etc --localstatedir=/var --enable-experimental-plugins --with-boost --with-hwloc --with-user=www-data --with-group=www-data I've included config below from records.config, stripping out things that were turned off and most things that were left default.

I get an unusual behaviour where content delivery stalls with consecutive requests. Across the archive whole, it's efficient and fast, but I can trip it up with a single client, and the apt-get process often stalls for individual users. I'm at a bit of a loss as to why. I've eliminated the L7 front end, and I've eliminated the content backends as the cause of the fault. If I remove ATS from the path, or talk to either end directly, the service is reliable and consistent. Is this HTTP or HTTPS ? Is there some setup / configs you can share, together with URLs / curl directives to try to reproduce ? - leif
