logrotate refused to rotate the logfile due to permissions:
```
logrotate[6248]: error: skipping "/var/log/cgrates/CGRateS.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation
```
Ownership of the directory and logfile is root/adm:
```
