11.31 System Memory too high

UNIX HP-UX
1

Hello, I noticed very high system memory utilization on my new 11.31 Itanium systems. System memory is more than 11GB on 32 GB system. Comparing this to 11.23 it's more than double ... How do I find out what is using it? Is there a way to reduce it?
Thank you,
Kubo

Hi,

First of all there is no memory in Unix. Please refer to it as space.

1) For checking the disk space first give the df -kh command and look for the file system that is occupying max space.

2) Give du -k file system with max space consumption to check for which file or folder is occupying max space.

Cheers

What do you see when you type swapinfo -tam?
Some java / firefox/mozilla running?

this is the output

# swapinfo -tam

as far as filesystem space, they are less than 50% utilized ...

Thanks,

Try to found wich proccesses are takeing up heavy memory with glance or top and maybe you will discover a proccesses wich are causing this issue.

I my servers I discovered a few proccesses (3rd party) wich give some problems in 11.31 and worked fine in 11.23.
