...since it occasionally causes queue backlogs on Heroku & it's not clear whether it's useful for sheriffs in its current form.

Bug 1301434 - Disable the detect-intermittents task by default

Since it occasionally causes queue backlogs and needs tweaking to be
useful for the sheriffs.

If the intention of this bug was that on treeherder.mozilla.org we would no longer put a hollow star on jobs that autoclassify has once seen be intermittent (as implied by bug 1301795 comment 3), it didn't work, we still do that.

This stopped running the task which goes out and tries to find new intermittent patterns (to supplement any matches made by a human), however I believe any already-found-and-stored patterns from this task, plus any previously made matches made by a human, can still result in the hollow-star, since that's part of the overall autoclassify task (which uses the list of "known intermittents" to assess new jobs).

Or to be clearer: stopping this task prevents any new "bad" patterns being added to the list of believed intermittents, but we likely (a) need to purge any existing "bad" matches, (b) make sure humans aren't teaching autoclassify the wrong thing still too.

James, could you clarify?
