This first occurred on a nightly Linux 32-bit PGO build.  The failures did not occur on the non-nightly build from the same changeset:

Is it reproducible on this build?

> Is it reproducible on this build?

Good question; I'll try retriggering to find out.

The following set occurred on a push that for some reason got four sets of M1/M2/M3 tests on a single Linux debug build.  Each of the suites failed once out of its four runs.  The mochitest-other suite ran only once and did not have the failure from comment 0:

comment 4 and comment 6 were from this Linux opt (not PGO) build where M1/2/3/other each ran once and failed: https://tbpl.mozilla.org/?tree=UX&rev=02fe687f8f52
In the cases where I retriggered, the retriggered tests were green.

The bug also doesn't seem associated with any particular slave(s).
Update: On this push, the retriggers failed too:
https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=2172873119db

Anyone want to download that build and do any manual testing?  I've archived it at

The reason being that "is it bad builds?" was my first question, and that was the first build I found where there didn't seem to be any funkiness about multiple builds on a push or any possible confusion about whether the retriggers would run on the same exact bits. Not reproducible on a given build, but the same set of failures happens in multiple suites on a give push? Touching a flaky network is the usual reason for that failure mode.
Related with bug 648429?
It seems that cacheAsFile may not be honored if the response is already cached.

Bug 661115?
If this is a symptom of bug #661115 I would expect it to be permanent, not orange.

Note that #bug 648429 do not compress requests with STORE_ON_DISK_AS_FILE.

(In reply to Matt Brubeck (:mbrubeck) from comment #3)
> and M1/2/3/other each
> failed the second time:

Do the test clear the cache initially? If something is left in the cache from a previous run of the same test or some other test, the compression introduced in #bug 648429 may cause confusion. I.e. if the first request is marked STORE_ON_DISK_AS_FILE the cache-entry will *not* be compressed. If a subsequent request loads the same resource without STORE_ON_DISK_AS_FILE, it may find the cached (uncompressed) entry but expect it to be smaller.
That set was talos-r3-fed-073, talos-r3-fed-073, talos-r3-fed-069 and talos-r3-fed-065.
And those two were talos-r3-fed-004 and talos-r3-fed-050
 talos-r3-fed-061
And those last two are the first time I've hit it while retriggering on a job that had failed the first time, on talos-r3-fed-046 and talos-r3-fed-054, neither of which were involved in the first round of failure there.
I started getting suspicious about the way that all of that explosion of retriggerable failure on inbound was on builds done by linux-ix-slave17, while in between builds done by linux-any-other-slave weren't failing, so catlee clobbered it. Of course it hasn't done a single build since, having taken up a life of building Android, where nobody even notices if none of your builds work right.
And yes, now that you mention it, those failures *were* on the clobber build by linux-ix-slave17.
That set, however, were on a build by linux-ix-slave33, and yesterday's debug were linux-ix-slave35.
