Dear mate,

We have 15000 series of hardware with 8 GB ram in the gateway (A/S cluster). Now we are facing 82% RAM utilization but traffics is low. Why? Sharing some output, please suggest

Mem: 7614 4673 1125 6 1816 1890

How many connections and what is the system uptime?

Irrespective please investigate upgrading the RAM for the longevity of the system.

Those boxes can have up to 64GB, most systems now ship with atleast 16GB by comparison.

As long as the system is not significantly dipping into swap space you are fine; only 9MB of swap has been reserved from a pool of 20,512MB.
