Continual crashes caused by copy, past, and move commands

Hi,

 

We have had an ongoing issue where AutoCAD will crash anything from 2-14 times a day. Annoyed with the situation we have gotten drafters to fill out a log that records the time of the crash, how long the crash took (estimates only) and what the last command was that was used.

 

What we have found is that the majority of incidents occur with copy and past and move related commands. Also a lot but not all crashes will prompt alerts including text like:

 

AutoCAD Aborting:

 

! FATAL ERROR: Unhandled Access violation reading 0x1cd0fb38 Exception at c987d7eh

 

I’m not a windows expert but know as much as to say that the 0x1cdfb38 refers to a memory issue, this coincides with the fact that the Move, Base point and copy and past commands select drawing items and stores it in memory while its being moved or awaiting a past location.

 

The problem cannot be hardware as we more than for fill the recommended system requirements for running AutoCAD 2009.

 

I have noted also that many CAD forums including this one have many topics in relation to the copy and past as well as move commands causing crashes. However I need the correct solution and not the other 99% that are listed.

 

Could anybody help to further pinpoint the cause?

 

Thanks-

"Type SCALELISTEDIT to see how many scale lists are in your source dwg. If you get an error message, it means the number of scales in the list exceed the editor's capability."

Whats your virtual memory set at?

 

To find this go

 

Start menu > Settings > Control Panel > System

 

When System properties show, click on the "Advanced" tab then Settings in "performance" section.

 

Another dialogue box should open, again Click on "Advanced" and in there it should show how much virtual memory you have.

Hi,

 

we have the same problem as this person is having in our office, what should be the correct amount of virtual memory or how do you change it.

 

Thanks

Virtual memory (i.e. - page file) should be 1.5X to 3X the recognized memory (this may not be the same as installed memory) especially if you are running WinXP.

 

It is recommended that you also set both the min and max values the same. This will ensure a contiguous space on your hard drive is set aside for the page file.

Your virtual memory is artificial memory that is created when your ddr memory runs out and it has to page file on your hard drive. Virtual memory is different for every machine and you shouldnt exceed the recommended manual settings unless you do your research. Like "skipsophrenic" said, once you are in advanced, click manual, it gives you a recommended amount based on the size of your disk. Follow that for maximum speed of page file. If you do more than what is recommended, it can actually slow your machine down.

I thought virtual memory is based on a multiple of the installed RAM and not the size of the hard drive. If what you say is true then a person could install only 512MB of RAM but use a 1 tetrabyte hard drive and have a page file the size of the state of Montana.

Your right, it sounds funny, and it should be a ridiculous page file. However, you are linked to transfer of the hard drive back and forth from memory, processor, hard drive, disk drives. It doesnt have an unlimited pipe that you can shove data through.

 

Think of it like a big vacation weekend for the family. You have your memory which is the airport. There is only so many flights that house data. Once the flights are full, you have to take the bus through the tunnel. Well you cant just send 5000 bus's to the same tunnel at the same time. Your limited on the amount of bus's. Otherwise you have a traffic jam of a huge page file transferring data back and forth and your machine will slow to a crawl.

 

The more memory you have available, the more page file. Plus with technology increasing the amount of cache that can be used for instant release of data, but your still limited by your system bus.
