Hello, Centos 8 does not do any maintenance anymore. Centos 7 is caused by the installation of the new version of rspamd, which causes the python library to not get the process name correctly.
It is recommended that you install the lower version manually, and if rspamd works you can ignore it
Rspamd daemon version 3.1
