Well, some more information is needed before one can start to look at this more deeply: - What is the Ubuntu release where this happened? - Was the system up-to-date? - Which syslog was used? - What is the version of the syslog package? (apt-cache policy <package>) - When did the last log rotation happened and did it worked? - Is there any indication in the logs that the service got stopped (by human interaction or by tools/application) or crashed? - Are there entries in /var/crash? - Any indication for problems with systemd? - Was this identified more than once (on this or other systems)?
