Topic: AutoCad 2006 memory leak or bad programming?!?

[whdjr]

I am having an issue where towards the end of our workday at our office (which is a 9 hour day) some of the Autocad sessions close automatically stating they have run out of memory.  I was wondering if anyone else has had any memory issues on 2006?

I was also curiuos if this might be caused by bad programming on my part.  What types of programming issues can cause memory leaks?

Depending on which language you use, creating things with 'new' and not deleting them with the corresponding 'delete' will cause memory leaks. Using key words similar to these allows you access to the 'heap' which is where you can use memory at run time for your application when you don't know how much memory you will need at compile time. If you use the heap, you have to give it back as soon as possible or that is exactly what happens.

I am not sure about plain 2006, but Civil 3D 2006 will free up considerable memory according to Task Manager by minimizing the application.

All my custom programming is done with Lisp.

Can't speak to 2006 but I've seen what looks like a memory leak when editing tables in 2005.

In fact with 2004 ADT if my PC starts to run really low on memory,thats one thing I do and it seems to help.

I use lisp..

there it is..
The first LSP file that AutoCAD read is ACAD.LSP...
He search this file from the AutoCAD search path directory...
so this path is network folder...called x:\acad..
you need to put this folder on TOP because if AutoCAd didn't find the ACAD.LSP in the first one...
he continue to search...

In this Acad.LSP file I load the setup lisp...

Setup lisp is diffrent depending our diffrent client..
so the program set the client in this drawing and load the variable from a txt file located on network..
also, this program allow user to customise there menus..

I've created this setup because to much client standard and to much program client use the (defun s::startup()...
so this is a pain...when trying to get more than one program running...trust me.

Also, you can use the PROFILE name to load what you need...

Code: [Select]

(setq CPROFILE (STRASE (getvar "CPROFILE")))
(IF (= CPROFILE "CLIENT1")(load .....))
(IF (= CPROFILE "CLIENT2")(load .....))
(IF (= CPROFILE "CLIENT3")(load .....))
that how it run here...
so if you have any other best solution.....
don't be shy.
