--MARK-- in /var/log/messages

[En]
Strange output in the /var/log/messages file as

Jul 30 22:13:18 localhost -- MARK --
Jul 30 22:33:18 localhost -- MARK --


this is a default option or the syslogd. With the man page of the syslogd,

 -m interval
              The syslogd logs a mark timestamp regularly.  The default interval between two -- MARK -- lines is 20 minutes.  This  can  be  changed  with  this  option.  Setting the interval to zero turns it off entirely.

also look at /etc/syslog.conf file.
