Memory overload

[Millwork]

Hello,

I am having a problem with memory. I am running Windows XP with 4GB ram. when i start laying out in paper space, i copy the window in one page or copy multiple pages, every time i copy a page of window my memory builds up & up & up with each one until it gets to over 2 GB & the it tell me that if i continue with this next process CAD will crash because i have maxed out the virtual memory. This is usually not a problem when i am doing smaller one off drawings with a few pages of windows but when i am doing a bigger project with 20+ pages or windows i run out of memory.

I gave the latest file to my business partner & he does not have this problem at all. He can open up many windows & as many pages as Cad will allow. His memory always fluctuates around the same 2GB. He is running Windows 7 with 4 GB ram. Any suggestions.

Hit it with a hammer.

 

Do you have any other programs running? If not it could be a virus.

[ReMark]

I think we need more information.

 

Are you running a 32-bit or 64-bit system? What about your business partner?

 

While you are working in AutoCAD what other programs are running in the background? Ex. - antivirus, MS Office, browser, etc.

 

Do you have any idea what your virtual memory settings are? Can we assume you let Windows manage virtual memory rather than actively settings it yourself?

 

When was the last time you ran a virus scan of your system?

 

How much free space is left on your hard drive?

To add to that, when was the last time you ran a disk defrag? Or even deleted your cookies/browsing history. Those take up a huge amount of space if left unchecked for a long period of time.

We were using the 3G switch for XP. See:

It is a 32Bit system, Dell Precision T3400, Intel core 2 Quad CPU, 2.49 GHz, 3.25 GB Ram.

He is running an HP Compac 500B Micrp tower, 32 bit, pentium duo cors 2.70 GHz, 4 GB Ram

 

 

Mozilla, excel & outlook

 

It was managing itself at 2GB until this morning when i manually changed it to 3 GB as suggested off autocad web site. They say this could back fire & i could have windows update problems in the future. Not sure if i should keep it at 3 or go back to standard 2. It did make any difference except allowing me to get a few extra pages before it hit the max of 3 GB.

 

 

Every day at 3 AM

I have 2 hard drives, C:drive has 26 GB out of 80GB free space. This holds programs.

F:Drive has 64Gb out of 74GB. This holds CAD drawings.

 

Anti virus is AVG & AVG 1 - click maintenance.

 

I scan disk & defragment about once every two weeks to 1 month but the above program does it on its own also.

 

I am running Autocad 2012 now & was running 2010 fora the last few years on this computer. I had the same problem running 2010.

 

In the past i broke up jobs into many Cad files so i could use the paper space i needed for each one before it maxed out. Now it is just getting annoying especially when i know that other do not have this problem.

I should also add that when Cad is off my computer is using about 400 - 450 MB of memory with other programs open, Excel, word, outlook, Mozilla,

Virtual memory is normally set by Windows to be 1.5X the amount of installed RAM. Some have suggested it should be set between 3X and 4X. It is also recommended that both the min and max values be the same so that Windows will set aside a contiguous space on your hard drive for the swap file. This means the space is static and does not grow or shrink as data is paged in and out.

 

If you have 4GB of physical memory and Windows is showing 3.25GB available then can we assume you are running with the 3GB switch enabled in your boot.ini file?

 

Have you tried shutting down all programs, with the exception of Windows itself and AutoCAD and see what happens?

Are you running a single session of AutoCAD? That is to say do you have one session with multiple drawings open or are you opening a new session of AutoCAD for every drawing?

 

Do you have hardware acceleration disabled?

 

Do you make use of layer filters?

[Millwork]

Remark,

I assumed it was set to 2MB because when ever it got up & just over 2 it would give me the notice that i was about to exceed the limit.

The #.25 Ram is what is showing in "View system information". I did the 3G switch this morning with the same results but it can get up to 3Gb before it give me the notice.

I an running a single session with only one drawing opened.

I can draw as much as i want in model space, it is only when i get into paper space that the memory starts to build up.

[ReMark]

Are you using a custom template file with your paper space title block and border already inserted?

 

Do you have hardware acceleration enabled?

 

Are layer filters being used?

[Millwork]

Yes i have a custom template that i use in paper space.

I do not know if hardware accelerator is on or off. Not sure where to look for this.

we are a cabinetry show so we don't really use layers that often. I don't know anything about layer filter.

[ReMark]

Hardware acceleration can be controlled via the 3DCONFIG command using the Manual Tune option.

 

What is the file size of the template file?

 

What about bloated scale lists?

[maratovich]

We have such computers.

Helps only 64bit OS installation or programs that automatically clears the memory.

Is it viable to purge certain aspects of your CAD file, to keep the file size down?
