Re: HP-UX 11.31 high memory usage
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?

Re: hpux B11.11.31 high memory usage
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
