Page File Usage Overload

My 9100 has always had a problem with using too much memory. If I don't turn off my computer every day the PF usage will go over 3Gb. I only have 2Gb of ram. This can take up to 3 days but with CAD running it happens much quicker. I'm very diligent about spy ware, I've had to clean my family computers more than once. My research into this came up with something called a memory leak.  It says that there are programs are not returning memory after they are no longer using it.  It also said it is very difficult to identify and repair. Any insight would be appreciated.

Hello again,

When all is said and done a 3GB page file is really not that large at all. I have mine set to 5GB min and max on it's own partition on a hard drive not used by Windows.

With the low price of hard drives these days, if 3GB's bothers you I suggest that you buy a much larger drive.

The page file is actually a file on the hard drive that Windows uses to swap things into and out of RAM quickly.

 

So:

1. How big and how much free space is available on your hard drive?

2. If the drive is fairly full, copy some files off onto CD/DVD and delete them from the hard drive

3. Click start>run

    Type in: chkdsk c:

    Click ok

    Accept offer to run chkdsk at next boot, and reboot; chkdsk will run before Windows loads again.

4. Defrag the hard drive

5. In XP, open System Control Panel.

    Click Advanced tab

    Click Settings button under Performance

    Click Advanced tab

    Click Change button under Virtual Memory

    Click System Managed radio button

    Click ok back to desktop and reboot

80 used 166 free. I've done all thses things in the past. The issue is that the system never gives memory back unless I reboot. So the system runs fine for a while but cannot run for long periods (2-3 days). I have a jpeg of task manager but I cant figure out how to post it.

Hello again,

Just some background information please.

What version of Windows do you use? How many hard drives do you have? What are the sizes of the hard drives?

The 80 used and 166 free? What are those numbers?

To post a picture here you can either upload it to a web server and then use the URL by clicking on the tree when you post. Or, you can visit my web site for more information on how to add the picture here.

i have 2-250 Gb HD. Approximately 80 used and 170 Free. Two drives set up as Raid 1.

I'm still looking into how to upload a file. I'm going to see if I can use the one at my web provider.

Hello again,

I see. If I might suggest ...

Adding another 2GB of memory to your system would seem to be in order since you say that you often use CAD programs. Crucial offers a 2GB kit matched to your 9100 system for about $38. It will help your CAD programs at least, and also help with any graphics or editing that you may do. More memory means less use of the swap file and equals faster response in those memory intensive programs.

From your posts talking of memory leaks ... There is nothing you can do about memory leaks except to stop using the programs that have them. The leaks are caused by bad coding and nothing can be done by the end user to correct them. The only recourse you have if you must use a program with a memory leak is to reboot your system more often. And again, the more RAM you have in your system the less effect these leaking programs will have.

If you need help in uploading your image file or posting the code here, feel free to message me here or use the email address at my web site.

It's not a bad idea to look into more memory. I'm not sure how mine is configured and if I have any open slots. I hate throw stuff away. I had tried to research this last year and I got stuck at this same point. The problem is how do you find out which program is responsible for the leak. The problem is more pronounced when running cad but doesn't go away when it's not being used at all.

Hello again,

The Crucial site will inspect your system and tell you what you have, and also what you can use.

Don't throw anything away. Donate it to a church or whatever. Sell it on eBay...

I don't know how to tell except by paying attintion to what you use.

But, I do not see any problem at all. With what you say you do, and what you say happens ...

I don't see anything out of the norm for a Windows machine using the programs you do..

It's your money, but before you start spending it, you might want to read some of these:

Find a memory leak that is bloating the Windows XP pagefile
A memory leak causes Windows XP to become unresponsive

A memory leak occurs in the Lsass.exe process on a Windows XP-based or a Windows Server 2003-based computer

 

And a whole lot more here.

Thanks, I'm  looking these.  So far it's not glaringly obvious how I'll find the offending program.  I think I've already verified that there is a leak. % committed bytes in use goes up as well as others.
