I think they've disappeared because our log rotation is too fast - I've now upped it to 30 days. I guess over time we'll figure out what we need in this regard, ideally we'd keep logs indefinitely but they're several megs per build. I've kicked off another build for this series and the links in Patchwork should update to point to the new job when it's done (probably in the next couple of hours). -- Andrew Donnellan OzLabs, ADL Canberra andrew.donnellan@au1.ibm.com IBM Australia Limited
