Finder memory size keeps on expanding
I have OS 8.5.1 and Nortons DD 4.01, I can leave my Mac unattended all day only to find the finder memory has bloated to +64MB. Also Filesaver can not run full check (on shut down) as it says that the disk is in use.

What are your memory settings? Is Virtual Memory on? What is your cache size? Those two factors affect your Finder's memory the most.

Virtual memory is off and cache is set to default (2048K)

This isn't an answer to the cause exactly, but the sharing of an observation... I have a 32MB Ram iMac which uses 14.5MB for running the system. I feel this is inexplicably high, but better than the 34MB the system uses when I turn Virtual Memory off! My virtual is currenly set at min. Effectively I am gaining nothing, but for the recapturing of nearly 20MB that I lose when it is set to "off" I would LOVE to know what is going on here. I have installed al available updates. When I receive the new Norton Utilities (one that works with this new system) I hope to find a real solution.

Steve -- for your problem, I have no idea whats going on. I would contact Symantec and see if they have any idea, since Disk Doubler seems to be the variable in that equation.

It is normal for the System partition to grow substanially during normal use, as the Mac OS uses "shared libraries". Shared libraries are bits of code that get used by several applications at once to conserve resources. However, the memory that shared libraries consume will almost always manifest in the System memory partition. It's nothing to worry about.

Jofo - Although some people have religious disputes about this, it really is best with the newer versions of Mac OS to have virtual memory on. In the past, virtual memory would only be used if Mac OS ran out of real RAM. That is no longer the case. In fact, having VM on actually reduces the amount of real RAM that applications require to launch.

This is a good idea in particular with the iMac and Blue and White G3s, as they use a new type of Macintosh ROM (NewWorld ROM), that loads itself into RAM. This makes the machine faster, but also takes more memory. Turning on VM significantly reduces this side effect, however. In fact, I would recommend turning VM up to 64MB on a 32MB iMac.

I have been using VM and Im not sure I like it. It reduces the demand for memory, most notably in the system software, but it leaves a shadow behind sometimes, especially when I am on the web. If Ive been on a page for a while and I go to hide the window or close it, it closes but, it leaves the image behind for a split second. Understand? I hate it. I have an iMac runnning with 96 MB RAM and i have the VM set to 97. Ive had it up to 150 MB but, it was the same problem. Any advice?

Croc, try fiddleing with your browser's cache settings, that may have an impact on your prob. As for VM and cache size, try setting the disk cache up one notch and VM to just one over the physical RAM size. Programs will load faster and your RAM requirements will drop into the ground.

I was reading the problems that the Guys in the other posts were experiensing and I started thinking about virtual memory.
I have a G3 266 with 256mb RAM, with vm turned off and the cache at its default.
My question is, Should I be using vm at the minimum setting so the requirements fall a bit down or don't I need vm with that amount of RAM.
 
Marc Norman Feb 12, 1999 06:26 PM
I think you should turn on VM to 258, you will see an decrease in loading times.

Here is the only cure>Use RamDoubler 8, set 'Advanced' controls to "Hold System Heap", and your Memory Creep problem will disappear. I guarantee it.

first off....OS8.5.1 has a documented Memory leak...upgrade to 8.6 at least.
second, if you only have 32 Mb RAM, buy more, it's less than a dollar a Mb now..in the mean time, with 32 real, set VM to 64, don't go much higher than double your real RAM. get at least 96Mb RAM for modern use, preferably 128+, i have 208 Mb and sometimes i have to quit apps.
third, be aware that RAM fragments just like a hard drive...try to quit apps in the same order you open them to reduce fragmentation. i have also had success with a combination of MacOS Purge, followed by a "force quit" of the finder, to defrag RAM...otherwise, just hit "Restart"

PM8500/G3-454 1Mb L2@227

208Mb interleaved EDO RAM...NO VM

ím running 8.6 on a PB 99, and have a similar serious problem with memory leakage occurring in strange circumstances.
The memory required to run system files starts at around 23-25 megs. Then it slowly grows, up to 45 megs; I recognize that shared mem use might be occurring, but I was at 45 with just IE5 and Audion running besides the finder.
Oddly enough, it also seems to get better at strange times. Any given moment it might drop 10-15 megs. Also, whenever I OPEN programs the problem alleviates a little bit (at least this is the case with Netscape (though not Word). Quitting them makes it worse.
I run Ram Doubler 8 w/ Hold System Heap chosen; it doesnít seem to make any difference.
Anyone have any ideas what my problem is?

Sorry about the snafu -
I'm a newbie.

Thanks,
Matt Lenkowsky

taking a stab in the dark... have never heard of or seen the extreme case you describe, 'dropping 10-15 meg' at any given time...

bad RAM?

maybe try deleting the Finder pref's, System pref's, Memory pref's, and why not toss these too:
Apple Menu Options pref's
ASLM pref's
Energy saver pref's
MacOS pref's
TSM pref's
and restart

I followed your instructions to the t, and it seems to have done the trick - Sys. ram use stable ca 20-25 megs, and no sudden changes.
many thanks.

But isn't it true that virtual memory slows down the computer? I've noticed under macbench that I loose a whole 200 points during cpu benchmarks. Any way around this loss in performance (also noticable in real time, such as when you have system sounds on, you hear more of those sounds when running the mouse through a menu without virtual mem rather than with it on)

I don't know if this applies to you or not, but many "disk is in use" errors can be due to file sharing. Turn off file sharing and see if your Filesaver problem goes away.
