Last updated on MARCH 07, 2014

Applies to:

Linux OS - Version Oracle Linux 5.0 and later
Linux x86
Linux x86-64

Symptoms

Newer systems which use the rsyslogd(8) logging daemon instead of the venerable syslogd(8) tool may find entries similar to these in the /var/log/messages file:

Feb 19 15:25:51 xc01db02 rsyslogd: WARNING: rsyslogd is running in compatibility mode. Automatically generated config directives may interfer with your rsyslog.conf settings. We suggest upgrading your config and adding -c3 as the first rsyslogd option.

Feb 19 15:25:51 xc01db02 rsyslogd: Warning: backward compatibility layer added to following directive to rsyslog.conf: ModLoad imuxsock

This is a cautionary notice because the newer rsyslogd(8) utility has much more capability and flexibility than the older syslogd(8) daemon. Users are encouraged to enable the extended features of rsyslogd(8); those interested should continue reading, otherwise these messages may be simply ignored.
