This is part of the paging process.

If process requires a new page and doesn't have a free page in its own set it will request a page from the free list - this generates a minor fault.

mf
minor faults -- but see the -S option for how this field is modified.
vmstat -S
Report on swapping rather than paging activity. This option will change two fields in vmstat's ``paging'' display: rather than the ``re''and ``mf'' fields,
vmstat will report ``si'' (swap-ins)
and ``so'' (swap-outs).
Increase your swap.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

The paging algorithm in the Solaris kernel is always on the hunt for pages not beeing used for a while. When a page has reached the timeout it put in a list called the free list.

If the page is needed again and it is found on the free list with all the contents intact it generates a minor fault. A major fault would be to take a new page and load the data from disk into this page, which ofcourse takes a lot longer.

It not really an error just the way the paging system works. It can be tuned but try it on a test system first.

If you are running anything but Solaris 8 put the line
set priority_paging=1
in the /etc/system file and do a boot -r to reconfigure the system.

Tip, if you have the Solaris Documentation cd there is a section on tunable kernel parameters.
