Raj,
At first glance, looks like you might have a memory bottleneck..with a high scan
rate value. Could you also send output of mpstat command together with "iostat
-xn" and vmstat all taken at the approx. the same time.
Might be able to get an idea, also what kind of software/appication is running
on this server, what is the Sun Server model? What is the server used for?
Regards..
