[syslog-ng] syslog-ng stuck on one CPU but need to share it with multiple CPUs.

[Mukarram Syed]

Hi,
I have syslog-ng version syslog-ng-2.1.4-1.el5 running on RHEL5.
When I run the top, syslog-ng process runs on only one CPU, but this is a 24 Core server.
How do I make syslog-ng share the load across several CPUs or cores rather than have it stuck in one CPU?
Any suggestions are appreciated.

TOP output for syslog-ng:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
11304 root      18   0 2023m 1.9g 1252 R 95.7  2.7  22658:29 syslog-ng
