Error description
When using 64k pages there may be paging space page outs of 64k pages even when VMM tuning indicates it should not be happening and AVM << real memory. This will normally occur when the demand for 64k and 4k pages is fluctuating.
Local fix
Problem summary
The customer will see 64K paging even though there are considerable 4K pages in memory.
Problem conclusion
The psmd algorithm is changed to be more aggressive in coalescing pages.
