Hmmm. Are you saying 'Ogres' are like onions?

Hi Foo
Could it be an application problem. It sounds like an application is
adding data to a possible type 1 file as a log or a como file or even a
print job and it is growing to an enormous size consuming resources.
There might be some other application that has gone rogue. Can you

Okay, it's AIX not linux, but I've just noticed that RAM = swap.
You are an ABSOLUTE FOOL if you do that on linux. Maybe (or maybe not)
the same applies to AIX - quite likely since they are both nixen and
probably manage memory

Kevin,
When you finally get this solved, let us know what the answer was. I
am sure all responders would be interested.

Please ignore my last post.
I scanned it and missed 'AIX'.

Kevin,
We had the same problem when migrating UV from DEC in one data center to
HP managed in another data center, even though it was a honking big HP.
The sys admins configured memory memory similar to how their 20 other
unix machines were set up. The trick was to configure most memory for
Screen savers? Best performance to background processes? On AIX?

Hello Kevin,
I have seen many good posts in reply to your situation already.
File-sizing, (and therefore disk IO) is a key/critical area.
What kind of file systems do you have?
How much memory swap space do you have?
What are the Virtual Memory AIX tuning parameters set to?

I saw /tmp mentioned in one of Scott Richardson's posts. UniVerse uses /tmp
for building select lists and sorts. If it is undersized, it can cause page
faults like you are seeing. How big is /tmp? It might pay to monitor it's
usage. It can be as critical as having adequate swap / paging
