With bots consistently red for long durations the dashboards seem hard to use - it looks like everything's broken all the time & it's not clear what are known issues with ownership and what are new/untriaged issues that need immediate attention.<br><br>- David</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><br></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Thu, Oct 1, 2015 at 12:06 PM, David Blaikie via llvm-dev <span dir="ltr"><<a href="mailto:llvm-dev@lists.llvm.org" target="_blank">llvm-dev@lists.llvm.org</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div><div class="h5"><div dir="ltr">This buildbot seems to have been failing for a while (though it's hard for me to identify the root cause in the logs, as I mentioned in another thread, so it's hard to say if it's the same failure, or if the failure is consistent, etc) - anyone watching it/caring aobut it?<br><br><div class="gmail_quote"><span>---------- Forwarded message ----------<br>From: <b class="gmail_sendername"></b> <span dir="ltr"><<a href="mailto:llvm.buildmaster@lab.llvm.org" target="_blank">llvm.buildmaster@lab.llvm.org</a>></span><br></span><span>Date: Wed, Sep 30, 2015 at 10:16 PM<br>Subject: buildbot failure in LLVM on sanitizer-x86_64-linux-bootstrap<br></span><span>To: Adrian Prantl <<a href="mailto:aprantl@apple.com" target="_blank">aprantl@apple.com</a>>, Ahmed Bougacha <<a href="mailto:ahmed.bougacha@gmail.com" target="_blank">ahmed.bougacha@gmail.com</a>>, Artyom Skrobov <<a href="mailto:Artyom.Skrobov@arm.com" target="_blank">Artyom.Skrobov@arm.com</a>>, Bob Wilson <<a href="mailto:bob.wilson@apple.com" target="_blank">bob.wilson@apple.com</a>>, Bruno Cardoso Lopes <<a href="mailto:bruno.cardoso@gmail.com" target="_blank">bruno.cardoso@gmail.com</a>>, Chad Rosier <<a href="mailto:mcrosier@codeaurora.org" target="_blank">mcrosier@codeaurora.org</a>>, Chris Bieneman <<a href="mailto:beanz@apple.com" target="_blank">beanz@apple.com</a>>, Daniel Jasper <<a href="mailto:djasper@google.com" target="_blank">djasper@google.com</a>>, David Blaikie <<a href="mailto:dblaikie@gmail.com" target="_blank">dblaikie@gmail.com</a>>, David Majnemer <<a href="mailto:david.majnemer@gmail.com" target="_blank">david.majnemer@gmail.com</a>>, Davide Italiano <<a href="mailto:davide@freebsd.org" target="_blank">davide@freebsd.org</a>>, Dehao Chen <<a href="mailto:dehao@google.com" target="_blank">dehao@google.com</a>>, Douglas Gregor <<a href="mailto:dgregor@apple.com" target="_blank">dgregor@apple.com</a>>, Erik Eckstein <<a href="mailto:eeckstein@apple.com" target="_blank">eeckstein@apple.com</a>>, Evgeniy Stepanov <<a href="mailto:eugeni.stepanov@gmail.com" target="_blank">eugeni.stepanov@gmail.com</a>>, Fiona Glaser <<a href="mailto:escha@apple.com" target="_blank">escha@apple.com</a>>, Hal Finkel <<a href="mailto:hfinkel@anl.gov" target="_blank">hfinkel@anl.gov</a>>, Ivan Krasin <<a href="mailto:krasin@chromium.org" target="_blank">krasin@chromium.org</a>>, Jingyue Wu <<a href="mailto:jingyue@google.com" target="_blank">jingyue@google.com</a>>, Kaelyn Takata <<a href="mailto:rikka@google.com" target="_blank">rikka@google.com</a>>, Kostya Serebryany <<a href="mailto:kcc@google.com" target="_blank">kcc@google.com</a>>, Michael Zolotukhin <<a href="mailto:mzolotukhin@apple.com" target="_blank">mzolotukhin@apple.com</a>>, Reid Kleckner <<a href="mailto:rnk@google.com" target="_blank">rnk@google.com</a>>, Rui Ueyama <<a href="mailto:ruiu@google.com" target="_blank">ruiu@google.com</a>>, Sanjay Patel <<a href="mailto:spatel@rotateright.com" target="_blank">spatel@rotateright.com</a>>, Vedant Kumar <<a href="mailto:vsk@apple.com" target="_blank">vsk@apple.com</a>><br>Cc: <a href="mailto:gkistanova@gmail.com" target="_blank">gkistanova@gmail.com</a><br><br><br>The Buildbot has detected a new failure on builder sanitizer-x86_64-linux-bootstrap while building lld.<br>
