I also see this on a system running stretch It is important to stamp out spam in Syslog
Many people use automatic log monitoring tools, e.g. syslog-nagios-bridge[1], to alert on errors in their logs. They only want to be alerted when something genuinely needs their attention. Or when looking at a report in LogAnalyzer[2], it can be hard to spot the real problems if there are lots of these more trivial messages. When a message is logged with this severity, it would also be useful if the message contained some type of call to action or link to further information (e.g. "please check X") Regards, Daniel 1. https://packages.qa.debian.org/s/syslog-nagios-bridge.html 2. https://packages.qa.debian.org/l/loganalyzer.html
