Hey maruel@,

Have you noticed any ongoing issues with swarming bots failing due to "Failed to start Xvfb or Openbox: [Errno 2] No such file or directory"?

No, I generally don't monitor task failure, just infrastructure failures. You may want to sync with labs to know if the base image changed.

Who should I contact about that?

Friendly ping on this bug, who can I contact about this? We have several analyses failing due to this today.

I spent the evening on issue 812860, everything was closed.

I looked at the bots that ran these tasks, in the same order:
https://chromium-swarm.appspot.com/bot?id=gce-trusty-113a80f8-us-west1-c-f04m
https://chromium-swarm.appspot.com/bot?id=gce-trusty-113a80f8-us-west1-c-rc2c
https://chromium-swarm.appspot.com/bot?id=gce-trusty-113a80f8-us-west1-b-rz2n

(you may have to click on "show more tasks" at the bottom once or twice) and when you look at the findit failing tasks, all tasks around are succeeding..
