Memory leak is when an app first starts and a call is put into the system for a certain amount of RAM to be reserved for its use only and then once the app uses it and runs it demands more RAM from the system as needed, but never 'remembers' to relinquish its un-used RAM back to the system. Some very bad programs even 'forget' to reliquish the RAM back when the are closed, so every time it is started a new call for RAM is sent. Eventually this eats up most of the available RAM and everything runs real slow or crashes. It is caused by miopic programming or bad programming. Your problem could also be bad RAM. One or some of your chips may have gone south, Are you using Generic RAM? Is there a warrantee? Did you run a RAM Checker program to test it? I found bad sticks in my G4 after about 1 year of use - some of the generic Ram is not perfect and OSX is very picky. jj On 27-Nov-04, at 9:46 PM, g4-request at listserver.themacintoshguy.com wrote: > How much memory? > To: "A place to discuss Apple's G4 computers." > <g4 at listserver.themacintoshguy.com> > Message-ID: <5C5A1626-40DA-11D9-8A7C-003065BF12BC at verizon.net> > Content-Type: text/plain; charset=US-ASCII; format=flowed > > > On Nov 27, 2004, at 7:07 PM, Wayne Clodfelter wrote: > >> Some will tell you that 1.5 Gb is all that OS X will use.
