Hi, I would like to thanks the following people for their replies:

The original question was:
--------------------------------------------------------------------------
We're running DU 3.2c on a DEC 7000 machine with 1 GB of real memory.
I'm trying to account for the memory. This is an approximation taken
when the memory is fully utilized (system is paging out consistently)
when there are close to 500 users in the system.
1. total of rss values in a ps output 600 MB
2. memory assigned to ubc
(from FS field in vmubc) 200 MB
TOTAL 800 MB
Where have the remaining 200 MB gone to? Am I missing something?
Our available memory shown in the uerf report shows approx. 998 MB.
Other details: VM field in vmubc shows approx. 800 MB
(ie memory assigned the the VM system)
ubc_borrowpercent=20 (which explains the FS value above)
How about wired memory? Are they included in the rss field of ps?
Anybody got any ideas?
Thank you all in advance.
Regards,
Chang

During that time, we had been running the Performance Adviser for more
than 1 week. Two days ago, I started to notice that the MIPC field of
the "vmstat -M" command showed a value of more than 90 MB and it continued
growing at a rate of approx. 2 MB per hour. When we stopped it, it went
down to approx. 2 MB.
The rest of the memory probably went to the kernel.
Regards,
Chang
