Every time SQL Server is started, the current error log is renamed to errorlog.1; errorlog.1 becomes errorlog.2, errorlog.2 becomes errorlog.3, and so on. sp_cycle_errorlog enables you to cycle the error log files without stopping and starting the server.
Execute permissions for sp_cycle_errorlog are restricted to members of the sysadmin fixed server role.
The following example cycles the SQL Server error log.
EXEC sp_cycle_errorlog ; GO
