[Rspamd-Users] Redis is constantly busy and need 12GB Ram

> Is it normal that RspanD establishes a hundred client connections to Redis at the same time.

How do you measure that? Are these established sockets or sockets in time_wait state?
How many mails do you receive in parallel?
Are there separate redis instances for bayes, replies, reputation, ...?

> I only have 10 email accounts and 1000 emails a day. But Redis is constantly busy. Redis is only used by Rspamd.

How do you define busy? One redis instance that uses 100% cpu all day?

> I limited Redis' maxmemory to 1G. Previously it was 12GB RAM with redis. How do I get this under control?

What kind of memory is that, resident (rss) or virtual?

Some people like to configure a separate redis instance for the bayes classifier and let redis evict old keys:
