I'm sorry. 
I attach a file of hb_report and pengine of the problem again.

I cannot understand your answer well.
I am because English is clumsy.

However, I tried the next setting.

 <nvpair id="rsc-default-meta_attributes-resource-stickiness" name="resource-stickiness" value="100"/>

The resource is arranged as expected when I make resource-stickiness 100 in the case of this time.

Will the meaning of your answer be this setting?

* I attached the file of hb_report and pengine of this setting(set resource-stickiness=100).

Best Regards,
Hideo Yamauchi.
