The log says that gizmo-noaudio.mp4-1 is suspended SOONER than we expected, but at least it is suspended. This does not break anything at the moment, but I will still keep an eye on it, maybe add more logs to check what happened later.

:kaku, thanks for looking into this- with 31 failures yesterday and we skip this job on many pushes (run it on linux opt every 5th push), the failure rate is a much higher percentage that 20%.  This appears to be opt/pgo and non-e10s only.

I will keep an eye on this as the failure rate puts this on the radar for a resolution by next week- let me know if there is more information I can help dig up!

Without any updates in this bug, it appears as if no one is working on this- the failure rate is very high and we would love to see this fixed soon.  One week out would be next Thursday and if the failure rate remains the same I will get a patch up for temporarily disabling this.  Ideally we won't need that as a fix will be close by.

[Tzuhao Kuo [:kaku]]

I apologize for not updating this bug, I thought I have done, but I didn't. 

The root cause is that the suspend-video-decoder is somehow mis-triggered before where we expected in the test_background_video_suspend.html, and bug 1347892 fix the issues of wrong policies for triggering suspend-video-decoder, so I believe bug 1347892 will fix this bug.

[Joel Maher ( :jmaher ) (UTC -8)]

great, I assume we will see this in the next day or two!  Thanks for the fix :)

[Joel Maher ( :jmaher ) (UTC -8)]

this seemed to have stopped on March 20th! I believe we can mark this as resolved!
