There are no endurance results available on Linux builds since Nov 18 Report: http://mozmill-release.brasstacks.mozilla.com/#/endurance/reports?branch=11.0&platform=Linux&from=2011-11-18&to=2011-11-21
Not sure why, but networking was disabled on both Linux boxes. I have restarted both and now it works again.
Please check if todays testruns are fine and verify appropriately. For now i have started them manually.
