rsyslog check failed

New issue today, I'm getting this email alerts every hour: lfd on my.server.com: SYSLOG Check Failed Time: Thu Mar 10 11:01:30 2022 -0500 Error: Failed to detect code [uAf6EKjqZ6NGNjeS] in SYSLOG_LOG [/var/log/messages] SYSLOG may not be running correctly on my.server.com I ran service rsyslog status and it does appear to be running. I did a full server reboot about 26 hours ago because the server load had skyrocketed (over 50 for several hours), so I'm ignoring errors from before that. The only errors after the reboot are: Mar 10 07:13:50 my.server.com rsyslogd[474]: imjournal: journal reloaded....] Mar 10 07:13:53 my.server.com rsyslogd[474]: imjournal: begin to drop mes...g Mar 10 07:13:54 my.server.com rsyslogd[474]: imjournal: 12058 messages lo...g Mar 10 07:13:55 my.server.com rsyslogd[474]: imjournal: begin to drop mes...g
Any other ideas?
