Конфиг syslog-ng

Pptp засоряет системный лог тупыми сообщениями о пропавших пакетах. Из-за этого /var/log/messages очень быстро разрастается. Направил сообщения от pptp в другой лог с помощью syslog-ng. Мой конфиг syslog-ng:

# The default action of syslog-ng 1.6.0 is to log a STATS line
# to the file every 10 minutes.  That's pretty ugly after a while.
# Change it to every 12 hours so you get a nice daily update of
# how many messages syslog-ng missed (0).
stats(43200);
