Oh right, I did a dev-side version of this, and forgot prod needs it too! (Maybe a bit silly to bother for a patch-level but whatever!)

; NOTE: It's generally recommended to pair this with a `MemoryHigh` setting, to
|
|
; try throttling memory usage before killing altogether. But at time of writing,
|
|
; our app has a memory leak that causes it to always keep growing - and then the
|
|
; throttling *successfully* keeps it within the RAM limits, just running very
|
|
; slowly. Instead, let's always reboot it when it gets too high, and hopefully
|

; find and fix that leak sometime!
