Redis has to be restarted every 14 days, otherwise sites slow down, what could be?

Question

Redis

after 14 days of uptime, sites start to slow down a lot (with a slight load), they looked for the reason, restarted php fpm - it didn’t help, restarting redis fixed the problem (response time returned to normal values). There was a similar garbage two weeks ago, they also restarted everything - it helped, maybe it coincided, of course, but it looks like a periodic problem, as if something is accumulating in redis.
there is a suspicion that the matter is in the standard redis configuration. Who will tell you what can eliminate the risk of a similar situation with site brakes or can help point out another possible reason?

Answer 1

what's in the radish logs? How much does it initially load on resources and how much after 14 days?
show redis.conf.
