How to limit the log file size created by a Linux service

A Linux service is creating a huge log file.

At the moment I am keeping it under control using cron (every X minutes I reduce it to the last X lines):

*/5 * * * * root echo "$(tail -n 1000 /var/log/XXX/logger_file.log)" > /var/log/XXX/logger_file.log

Is there any other way to do the job in a cleaner way?

The first line, after the cut, can even be damaged if the chars cut is size based (i.e. keep the last 1024 bytes).

Of course I cannot modify the service itself to keep quiet.

I hoped there is a setting somewhere to avoid the use of external commands. If it was system managed it would have dropped extra bytes as soon as the maximum file size was reached, instead of a temporal check with an extra command in cron. Logrotate is powerful indeed. Thank you.
