<font size="-1"><font face="Helvetica, Arial, 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>

(and others) got around this problem by launching multiple syslog-ng

I think I remember hearing that syslog-ng 3.2 was going to use threads
