1: Your certain everything works like it should ? RHEL 7/8 come with `needs-restarting`
2: See 1 (reboot ?) Or restart the effected services. (For Example)
# for s in auditd rsyslog irqbalance messagebus acpid haldaemon postfix ntpd abrtd crond atd rhsmcertd network; do service $s restart; done
3: dmesg / journalctl / top for starters.
4: Zero !

find /var/log -type f -iregex '.*[^\.][^0-9]+$' -not -iregex '.*gz$' 2> /dev/null | xargs tail -n0 -f | ccze -A
