kernel message ===mark=== what does this mean?

Hi All,

Sometimes I see the following line in dmesg:
=== mark ===

Does anybody know what this means?

Best regards,
Cedric

It means nothing.  It is a heart beat put there on a periodic basis as a marker.  This way the logs are guaranteed to be touched occasionally.  It allows one to approximate when a system died by when looking at the logs when there are no other meaningful data posted at the time of a crash.

If you want to get rid of it, use

mark_freq(0);

in the 'options' section of /etc/syslog-ng/syslog-ng.conf
