Please reboot the buildbot-masters this weekend, or at the next appropriate/cycle time. We have a new kernel for CentOS 6.5. (bug 1330695) :dividehex manually rebooted the following buildbot-masters as a test of the update: buildbot-master51.bb.releng.use1.mozilla.com buildbot-master01.bb.releng.use1.mozilla.com The slaves should already have the new kernel in the golden image. Thank you!
This turned out to be a bit messy because the master restart script didn't have any clue about bug 1323457 (filed bug 1340925 to fix that) so I ended up with a bunch of manual work. The windows tests masters in AWS also didn't come up cleanly - they were running and workers were attached, but no jobs were starting - and needed a 'make stop; make update start'. All the buildbot masters are restarted now.
