How limit pflog size

[reza.mnp]

how i can limit pflog size in /var/log path or rotate this file (clean this file)

[vmz]

for clean and rotate, try to create a script like this and add it in cron

#!/bin/sh
DATE=date '+%d-%m-%Y'
cp /var/log/pflog /var/log/pflog-$DATE
:> /var/log/pflog

That file isn't normally there, some change must have been made or package installed that changed the default behavior.

Normally the pf log is written to /var/log/filter.log which is a binary circular log that can never grow in size.
