Solaris Mem Consumption

We have Sun OS running on spark :

SunOS ciniwnpr67 5.10 Generic_118833-24 sun4u sparc SUNW,Sun-Fire-V440

Having Physical RAM :

Sol10box # prtconf | grep Mem
Memory size: 8192 Megabytes

My Top Output is :

130 processes: 129 sleeping, 1 on cpu
CPU states: 98.8% idle, 0.2% user, 1.0% kernel, 0.0% iowait, 0.0% swap
Memory: 8192M real, 343M free, 2282M swap in use, 2195M swap free

Which shows about 7 gigs of RAM already consumed.

My sar -k shows :

SunOS ciniwnpr67 5.10 Generic_118833-24 sun4u 08/07/2008

07:29:53 sml_mem alloc fail lg_mem alloc fail ovsz_alloc fail
07:29:54 4184032128 4044621477 0 901931008 621211704 1 1723777024 0

And if i under stood it right then i have around 4044621477 + 621211704 + 1723777024 Bytes of memory or 4.5 gigs used by kernel itself ??

If it is true then it i think some thing is wrong with my solaris installtion Any suggestions pls ?

Your system looks OK to me.
Pls update your kernel patches (esp Recommended cluster) to the latest of Solaris 10. There's much bug fixes to 118833-24 . No worries..

SmilieAnd not to forget, as a rule of thumb, swap device should be configured double the size than of your physical memory. (16384)
V440 is a stable server. Yours should keep going.

well here is the issue ..:

As per Top i am using 7 gigs of RAm.. now the moment i run some thing else then the current applications it page outs increases significantly from almot "0" to 4ooo +

That is causing the new processs to take more time ..
