Example: Btup builds started to also fail intermittently with the message from [https://bugzilla.mozilla.org/show_bug.cgi?id=1411358 bug 1411358]. The logs for these jobs showed no output before the timeout got hit, often even for more than 40 minutes. [https://bugzilla.mozilla.org/show_bug.cgi?id=1480494 bug 1480494] got created and because the scope was only on that build type, investigation by developers started quickly. | Example: Btup builds started to also fail intermittently with the message from [https://bugzilla.mozilla.org/show_bug.cgi?id=1411358 bug 1411358].

If a task fails with a message mentioning "ADBError" or something which starts with "ADB" and ends with "Error", it's a failure returned by the phone which runs the task to the controlling computer. Each failure message needs its own bug (e.g. for "init failed", "failed to create directory" etc.) | |||
