When a file size increasing overtime, use truncate, but without changing anything to the file permission and other stuff that applied to it. Best with adding it to crontab.
truncate
crontab
-s is set limit file size e.g. 1024k
-s
$ truncate -s 1024k /var/log/kern.log
Unfortunately, this shortens the end of the file, which reduces its usability.
Luckily, you can set limit the file size.
