logrotate: What means the message "log has been already rotated"
May be logrotate will be only on the second run begin to rotate log files. Seems that if no entry for that file is in /var/lib/logrotate/logrotate.status logrotate will be not rotate the file. So the trick was for me to change in /var/lib/logrotate/logrotate.status the line
"/var/log/capp/server.log" 2019-4-1-7:0:0
to
"/var/log/capp/server.log" 2019-3-31-7:0:0
... and logrotate began to rotate the server.log file
