Memory Leak
I purchased my first Mac about 11 months ago: a Power PC Mini. Loved it. Exactly what I wanted to run 24x7 at home. When the core duo units came out I bought one and sold my Power PC Mini to my sister.
The new unit requires a reboot every day basically. If I run it for 2-3 days it requires a hard boot. By the second day it can take a program a minute to respond to a mouse click. The hot corner screen saver/system lock will not respond after 3 days. etc etc. NONE of these problems occured when using the Power PC Mini for the same purposes : Streamin music in ITunes, surfing the web, and access my servers via Citrix Metaframe. The Power PC unit would go for weeks without missing a beat.
I've tried Apple then Googled a while, but can't find many Power PC mini's much less a great deal on one. Thus I thought I would see if this is a known issue, perhaps with a work around? I've been repairing PC's/Networks for 15 years: were this a Windows box I would say there is a really serious memory leak going on, but can't say this with certainty as it's a Mac.
The system is a Mini Core Duo 1.66 Ghz, half gig of memory, running OS X 10.4.8
Should I be able to use this unit as I did the Power PC one?
Thanks

It does sound like a memory leak. But it could be a heat problem too. Is it well ventilated?

I would not turn down another 512mb for your machine if anyone is dying to give you one. But if this is a memory leak then here are two possible directions. The first is harder:renicing
open terminal and" Find the process ID in top or ps -aux, and then type
code:
--------------------------
sudo renice x y
--------------------------
where "x" is the priority you want to assign (from -20 [not nice to other processes -- hogs CPU] to 20 [very nice, put on the back burner]; set to 0 to return to default) and y is the process ID.
or easier, here is a link to a utility:

Also, are you using Safari for the last two? Use to was that Safari was known as a memory hog.

Thanks for the thoughts thus far. I did want to put another half gig in the new Mini however it was a lot harder to open it without causing damage than the first one, so I gave that thought up for now. My thinking was the Power PC Macs seemed to do so well with FAR fewer hardware resources, thus what I would put on a PC ( 1 Gig then if not a hard working unit ) translated into half a gig.
Could one of you point me toward a cheat sheet for working on OS X? Keyboard combo's or other ways to pull up detailed system info? Has anybody created a Mac tool like Systernal's Process Explorer?
Will print this out to take home and try a few things. Thanks again.

I don't know the app you mentioned but the link on my previous post is for such a utility .
Activity monitor, as mentioned above, is also built in to os x

Finally had time of my own to dig a little. Started from the bottom of the thread and worked my way back up. The points were split because the simple term I was after is 'Activity Monitor': I had no idea what the utility was named within OS X. However many of the links Pheidius posted helped to flesh out, at least a little more, my picture of how OS X works.
I have to assume I either have a defective unit or the poor luck to run apps that leak a bit in that I haven't heard a call to arms about going from booting once every few months to every day. I just rebuilt my Win PC so will try running Citrix Metaframe on that for a week or two and see if that's it. If not the only other choices are iTunes and Safari.
Thanks for the posts.
