Why does redis eat all the operatiu?

Question

Redis

Good day.
Tell me please, what could be the problem?
There is a project that is hosted on 2 servers, between which there is a balancer.
The project is on laravel, and redis is used as a cache driver.
There was a problem, and the problem is that redis eats up all the RAM after a while.
I stop the balancer, then redis still loads the operative for some time, but gradually normalizes.
The second moment, when I clear the cache with the help php artisan cache:clear, it also normalizes, and then takes off again after a while.
The redis-a config did not change after installation.
Tell me, can anyone come across?

Answer 1

redis keeps all data in- line , periodically flushing it to disk if out of the box. The latter can be disabled through the settings
