Are you sure it's a problem? You're probably looking at memory allocation, not memory utilization.

Try the following:

[bigip-01:Changes Pending] ~  free -m
             total       used       free     shared    buffers     cached
Mem:         16077      16010         66          0        365       4079
-/+ buffers/cache:      11566       4510

From the command above, it looks as if nearly 100% memory is used but in reality only 11566 MB out of 16077 MB are allocated to buffers. That's about 72% true memory usage and not 100%

yes I have checked that free -m total - 5679 used - 5595 free - 84 swap - total - 1023,used - 91, free - 932. so in the case we need to increase physical memory, if so please suggested how to do that.
