I tried the job a couple of times; Failed when running on the same VM; * https://chromium-swarm.appspot.com/task?id=3806fb45b2d9a610&refresh=10&show_raw=1&wide_logs=true * https://chromium-swarm.appspot.com/task?id=3806a3ff32593110&refresh=10&show_raw=1&wide_logs=true Succeeded when running on another VM; * https://chromium-swarm.appspot.com/task?id=3806a414f855ce10&refresh=10&show_raw=1 Looking at the bot, it seems to be failing browser_tests too... * https://chromium-swarm.appspot.com/bot?id=vm989-m4&sort_stats=failed%3Adesc

The vt_video_encode_accelerator_mac.cc are likely a red herring -- they just try to create a hardware decoder for sandbox warmup. The tests themselves listed above don't use hardware decoded video.

So it looks like about 50% of the Mac 10.9 bots fail running the same set of tests; https://chromium-swarm.appspot.com/tasklist?c=name&c=state&c=created_ts&c=user&c=bot&et=1502975880000&f=user%3Atansell%40google.com&l=500&n=true&q=state&s=name%3Aasc&st=1502980200000
