In a few places, we assume that Heroku restarts our processes daily -- for example the in-memory caches for worker info.

We could try to find and fix all of those places -- it's a bit sloppy, really -- but we'll still have a risk of memory leaks in Node, etc. causing processes to fail.

If it's not too difficult, it might make sense to automatically restart processes on a daily basis (but not all at the same time).

Thoughts on which direction to go?

Makes sense to restart daily for sure.

It looks like k8s doesn't have built-in support for that, so I think this will need some kind of custom support in the services themselves.
