Re: swapinfo output...query..
Look at
ftp://eh:spear9@hprc.external.hp.com/memory.htm
For a good explain of swapinfo
The line reserved is memeory which is held in case of a program swapping thus not available for use. It does not show up in the 44% since it is reserved

Re: swapinfo output...query..
Memory usage is at 21,760MB. The same amount of swap space will be reserved, to allow for swapping if required. Your defined swap space is 18,130MB. what you will find is that you are now using 3,630MB of real memory for swap reservation.
I would add further swap to stop real memory being 'eaten' up by swap reservation.

Re: swapinfo output...query..
This isn't important. What's important is if you are getting Page Outs from vmstat(1).
Perhaps the system used more swap in the past?

This has long stopped working.
>Berd: I would add further swap to stop real memory being 'eaten' up by swap reservation.
Why? There is 27 Gb free.
