Tuning processor jobs on RHEL 5

[Wahyu Darmawan]

Hi expert,

I need your suggestion. I have 2 quad core processors (8 CPU) on my server and have installed kernel 2.6.18-92.1.18.el5PAE on it.
But, I have problem while running lotus domino service. The CPUs couldn't want to transfer jobs to another processors that idle.
Could you give me some advice to solve this problem?
And, how to create grouping CPU on RHEL 5, to make balancing processes?

Thanks,
