[syslog-ng] How to stop repeated messages in Syslog-ng?

Hi, folks. I am using Syslog-ng as a Cacti's plugin. There are some messages which had been logged since last months. I'd like to ignore these specific messages, I mean, stop to login them. I tried to turn ON two variables in the php.ini... ignore_repeated_source = On ignore_repeated_errors = On ...but unsuccesfully (at least, I changed them and didn't restart any service...is it required?) Is that possible to stop them?
