Admit I am confused here : Do I need two redis instances?  By instance I 
mean deamons ( current systemd only launches one deamon of redis) . One 
for "standard default rspamd keyvalues" and another instance for 
"bayes"?  I have just one instance on localhost:6379 - If two are 
needed, then this would seem to tie in with what you wrote. Can Bayes 
just be put in sqlite?  I thought I had this in sqlite afore in rspamd. 
I don't know Redis.

Added,
    servers = "localhost:6379";

    * configwizard statistic was run last year. Should I run this again?
