Filed by: rvandermeulen [at] mozilla.com https://treeherder.mozilla.org/logviewer.html#?job_id=3552229&repo=mozilla-aurora https://queue.taskcluster.net/v1/task/HN8j8-VrT8et1MZ78eg68w/runs/1/artifacts/public%2Flogs%2Flive_backing.log I really have no idea where to put this since it's not clear if it's an issue with how we're configuring our ASAN test slaves on Taskcluster or something else.

I don't see this on trunk, though. Did we fix this issue there already before they went to Tier 1? Maybe said fix can be backported to 50?

Joel, is it possible that we changed the instance types these run on at some point between 50 and 51?

in irc, aurora is running desktop-test-xlarge, I don't see any changes for trunk branches, it could be in-tree configs or something- we will merge in 2 business days- what is the rush?

Presumably they'll still be frequently failing on Beta for the duration of that cycle too...

It's worth noting that buildbot GTest has been timing out on aurora - bug 1115253. The TC instance type appears to be c3.xlarge, which seems right to me.

According to https://treeherder.mozilla.org/#/jobs?repo=try&revision=7e67649a365cedb0c2c79e575f4d4f37b7fa551d&group_state=expanded&noautoclassify&filter-searchStr=aa0b3558297f2348c36d172446a31d67b580e747 we should expect to see a lot of this again with 51 on beta, like maybe a third this, a third the "timeout" which totally isn't a timeout, it's bug 1303927, and a third green.

Oh, that's why I'm suddenly having to star as this on esr, Treeherder removed the annotation that was hiding it.
