Heroku dynos swap to disk before auto restart!
Memory used above quota will swap out to disk, which substantially degrades dyno performance.
If the memory size of your dyno keeps growing until it reaches five times its quota (for a 1X dyno, 512MB x 5 = 2.5GB), the dyno manager will restart your dyno with an R15 error.

You don’t want “SUBSTANTIALLY DEGRADED PERFORMANCE” do you? Of course not.
Whacamole will help you monitor and restart your dynos yourself.
