Since this looks to be the same error as bug 966408, I'm making this a P1. Doing a needinfo to myself to assign this once we have a final owner for bug 966408.

Likely the same error as bug 966408.

Like many MacOS failures, there is no evidence that the test has started. Unlike the MacOS failures, this seems to be happening in a single test.

Apparently something changed and was uplifted to Aurora 28 late Jan (bug 966408 comment 2), but now might be fixed on central and aurora 29.

Pretty sure it's hitting the network, or hitting the network's more insidious cousin, relying on a DNS query to return in a prompt manner - at the same time as that rash of failures, we also had massive numbers of slaves disconnect from their masters, indicating network troubles in the datacenter which didn't bother any other running tests, only this.

I don't know how this would use the network, at least not in any way different from other web audio tests. This adds some logging to get some clues re where the test got to: https://hg.mozilla.org/integration/mozilla-inbound/rev/d0b53dd1dcf0 I now see that webaudio.js is included, but not used, so I could eliminate that from the test too.

Removed webaudio.js https://hg.mozilla.org/integration/mozilla-inbound/rev/bc28c2b0b96b and using dump() for state to work around bug 974073 https://hg.mozilla.org/integration/mozilla-inbound/rev/afe584159bb2

Looks like bug 916387. https://hg.mozilla.org/integration/mozilla-inbound/rev/36335b77688e should stop the timeouts
