I bet your system with 60% idle has the CPU you are on 100% in the kernel.
Like Tanel suggested what does truss show?

How long has server been up?  May be problem coalescing memory.
What's chance of reboot and what did your SA have to say about this?
Did he open a ticket to SUN(Oracle) for this?

Another Update I found that if I am making call which is not sorting anything 
then it works fast on OS like simple ls command while ls -ltr or ls *.sql are 
really hang. 

Anybody saw such issue

i had one big OLTP environment running on Solaris 10 with 256G RAM and 30+ CPU. 
There are sometime in a day when all OS command are totally freezed. Even ls 
command take several minute. CPU was showing more than 60% idle. If I am 
connected to database, then call to check Db like locks or other query works 
fine. What can be the issue to be checked more closely. Also Application trying 
to connect from outside are affected.
