[syslog-ng] Limit logging frequency of specific messages?

Hi, This morning a daemon went nuts and sent enough messages to fill up my logging partition in a few seconds. As this partition is under /var (/var/log) this made some other parts of my system unhappy. I think I've fixed the particular problem that led to my system's self-inflicted DOS but got to wondering if there's a way that syslog-ng could limit the frequency with which it logs certain user-defined messages. Something like iptables' limit match: -m limit --limit 15/hour --limit-burst 30 I haven't found a way to do this with syslog-ng 1.6.5 (debian sarge). Is something like this feasible (or better, planned for a future release) (or best: already there)? Thanks! Frank
