Hi

you can use top or glance to see what process are consuming memory.

What is showing the high usage?  Are you having any performance problems?

Generally a high usage is a good thing, as long as you aren't swapping.

What does "swapinfo -tam" show?

How do you know that it is high and not normal? Have any configurations such as databases changed recently?  As Dennis said, high memory usage (more than 95% for instance) is a good thing since memory is expensive and it serves no purpose not to be used. If memory usage is high, first sort the processes into memory usage with this command (exactly as shown):

    UNIX95=1 ps -e -o vsz,pid,ppid,args | sort -rn | head -20

The processes will be listed largest first.

But that isn't the only use of memory. There are shared memory segments:

     ipcs -bmop

And the buffer cache:

    kcusage filecache_max
