Sql Server Error Log

Hello TechNet,

We are using SQL 2008R2 in our prod env. I see there are error log files are set to Max (99). We don't have any job in place to execute sp_cycle_errorlog. But 99 log archives are not showing logs for more than 15 minutes. When I expand any of those logs to inside they have message:
