Heroku auto restart dyno on H12 Request timeout errors : <p>We have a node dyno processing small API requests, ~10/second. All requests complete in under 0.5s</p>

<p>Once every few days, dyno starts giving H12 Request timeout errors on all requests. We couldn't discover the cause. Restarting fixes it.</p>

<p>How to make Heroku automatically restart the dyno on a H12 Request timeout threshold, e.g. more than 5/second?</p>
