<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica","sans-serif"'>The
way I do it is with separate init scripts and separate configs. The scripts
launch the additional processes with args like '-f
/etc/syslog-ng/syslog-ng.515.conf -R /var/lib/syslog-ng/syslog-ng.515.persist
-p /var/lib/syslog-ng/syslog-ng.515.pid'. That config then has a tcp source
driver listening on port 515, and the master process just sends traffic to
localhost:515. You could use pipes or whatever transport you want, I just chose
TCP.<br>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica","sans-serif"'>I
(and others) got around this problem by launching multiple syslog-ng processes
and having a master process do very basic filtering and routing to the child
processes.<br>
I think I remember hearing that syslog-ng 3.2 was going to use threads (at
least for destination drivers) but dont quote me on that.<br>
