<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>
