Getting the following error on the Rspamd webui. Code: learn error: Unknown statistics error, found when storing data on backend; classifier: bayes Noticed the error and I thought that the redis database was corrupted. So stopped the redis, Renamed the redis database file. Started the redis again Redis created the database file. Unfortunately the same error is appearing. In the /etc/rspamd/local.d/classifier-bayes.conf, if I comment out auto-learn there is no error. So definately it is a learning error. Anyone else see this error? On Centos 7, the error does not seem to be there. Anyone can verify?
