[syslog-ng] Unix datagram

Hello fellows. I will try to be brief with my question. I am integrating a team that is developing a system where syslog will receive messages and according to some match expressions will have to send those messages to another process. So, to do this, I have tried unix-dgram. I use Linux Ubuntu and what happens is that when I reload or stop/start syslog I get CORE DUMPED. I have made some research in the documents trying to find out the reason. What I understood was that unix.dgram only works in BSD. Is this the truth? My solution so far is to use a named pipe instead of an unix datagram socket. Tell me your opinion please. Regards, Bruno.
