Are you by chance using either flunearyou or wwlln?

[sgrayban]

Oh wait -- those are addons. I am using wwlln.

[bachya]

Got it. These messages are coming from the aiocache library, which the wwlln integration uses. It's unfortunate, but the aiocache author(s) decided to include these very debug-focused log messages to the info level; nothing we can do about that.

That said, this is just a notice that aiocache can't utilize either Redis or memcached in your install; it isn't a problem since wwlln uses an in-memory cache and isn't something we need to be concerned about.
