rsyslogd: imfile error: message received is larger than max msg size; message will be split and processed as another message

Issue

• When enabling log forwarding in RHOSP, the rsyslog container shows an error saying that messages larger than the maximum allowed size have been processed:

  [heat-admin@overcloud-controller-0 ~]$ sudo podman logs rsyslog
  rsyslogd: imfile error: message received is larger than max msg size; message will be split and processed as another message [v8.1911.0-7.el8_4.4]
  rsyslogd: imfile error: message received is larger than max msg size; message will be split and processed as another message [v8.1911.0-7.el8_4.4]
  rsyslogd: imfile error: message received is larger than max msg size; message will be split and processed as another message [v8.1911.0-7.el8_4.4]
  

• Same error will also appear in /var/log/containers/stdout/rsyslog.log
