Memory issue on solaris10 box
my system has 128G of installed memory. top, vmstat shows the system has just over 10G of free memory on the system. but as per prstat o/p the usage is just 50-55G is there anyway i can find which process/zone is using more memory ?

System has 3 zones and all running application servers.

Unused memory is wasted memory so there is no problem with the values you show.
No hidden process is using more memory. The kernel certainly does but will release most of it should demand occur.
What displays this command:
Code:
echo ::memstat | mdb -k
