Thanks to Dr. Tom and Paul for their responses.
The answer (simple enough) was to examine the VSZ (virtual size) and RSS
(resident size) of all processes on the system to see who had the biggest
chunk and who was gradually increasing their usage over time.
This was achieved with the command "ps axv". This command also showed %MEM
which is useful too.
The culprit was then easily identified as being the Compaq Command Console
Agent. SWCC RA200 Agent version V2.2-503
This has since been disabled until a solution is provided by Compaq.
Thanks.

Subject: V5.1 and swap space being used up
Hi all,
We have setup V5.1 on a test alpha and with nothing running, other than
standard Tru64 Unix we are seing our swap space being used up over time.
For instance in 24 hours when the system was not used by anyone, and
there was nothing running other than standard Unix our swapon -s went
from:
Swap partition /dev/disk/dsk1b (default swap):
Allocated space: 470784 pages (3.59GB)
In-use space: 1 pages ( 0%)
Free space: 470783 pages ( 99%)
Total swap allocation:
Allocated space: 470784 pages (3.59GB)
Reserved space: 13365 pages ( 2%)
In-use space: 1 pages ( 0%)
Available space: 457419 pages ( 97%)
to:
Swap partition /dev/disk/dsk1b (default swap):
Allocated space: 470784 pages (3.59GB)
In-use space: 1 pages ( 0%)
Free space: 470783 pages ( 99%)
Total swap allocation:
Allocated space: 470784 pages (3.59GB)
Reserved space: 44143 pages ( 9%)
In-use space: 1 pages ( 0%)
Available space: 426641 pages ( 90%)
That looks like some sort of memory leak to me. I can't imagine it is
normal behaviour. Should I be looking at any other information on the
system?
When left from Feb 18 until Mar 30 without reboot it eventually hung
when it ran out of swap space with messages such as:
Mar 30 15:24:18 pha302 vmunix: swap space below 10 percent free
I thought it may have been the application we were running, but this
weekend the app has been switched off and still swap is being consumed.
Any ideas? Do the latest patch kits address this?
TIA.
