That's pretty much the case with Log::Dispatch::FileRotate, a given file
size, and a max value of 1. If somefile.log grows larger than 'size'
bytes, it'll move it over to somefile.log.1 and moves it over to
somefile.log. Alternatively, you can use an external rotator with
similar settings.

If you don't want to roll over, but truncate the logfile in this case
(although this seems weird, as you might end up with an almost-empty
logfile at times), you need to write your own appender as outlined in

     http://search.cpan.org/dist/Log-Log4perl/lib/Log/Log4perl/FAQ.pm#How_can_I_write_my_own_appender?

That's exactly what Log::Dispatch::FileRotate does if you call it with
a max value of 1.
