NO ROOM TO ADD HEAP ENTRIES

[7come11]

Can anyone shed light on this Inventor 7 error?:

"NO ROOM TO ADD HEAP ENTRIES"

[Anonymous]

If you search this newsgroup you will find lots of
info...

I was getting this error all the time, and then I
read a suggestion to change the size of the undo file to 1000
( Tools->Application Options. Change "Undo file size (MB)" 
I have seen no errors since changing this value (was 256 previously)

Hi Brad,

Thanks for your response. I have the undo file set for 1000mb and I still get the no room error on ver large files. In fact, despite our and our dealer's best effort, we've been experiencing a great deal of trouble with large assembly performance in general. We've jumped through quite a few hardware loops too.

I had this problem emerge on an assembly of 400-ish parts and I've heard tales of Inventor working well on assemblies of many more parts. These performance issues have cause me and my upper management to set Inventor and MDT aside in favor of continuing in 2D for most of our applications. We feel frutrated and defeated.

What are your computer specs? What is the virtual memory setting?

The funny thing is, after 2+ weeks of good fortune,
I got the "heap" error again a few hours after responding to your post.  My
assembly is 50ish parts, simple geometry, but uses lots of derived
relationships.  Breaking some of those derived relationships
helped, but Inventor is still sluggish with this assembly.  Task
manager shows my ram plummeting to near zero as INV tries to open the
assembly.

I have Dell 650, WIN XP, INV 7, 1 gig ram, 900xgl
quadro, all service packs.

Are you saying that Inventor is consuming lots of memory then suddenly
starts using less? If so, are you using the /3GB patch and switch?

As the "problem" file is opening my RAM goes to 2000-3000, then after the
file opens, the RAM goes back to 400,000. (I have 1 GB total) By RAM I mean
available physical memory, as shown in Task Manager.
I am not using the /3GB patch and switch.

Is this anything that I can help with?

In my experience this can have either a simple solution
(undo file size, use the /3gb switch or something else) or be a problem with an
actual file low down in the hierarchy.

We are trying to put a lot of effort into addressing many
problems that are reported in this newsgroup to improve the quality of the next
release. We can only do this with the help of our customers. Therefore, I would
be very interested in getting a hold of the dataset that is causing this
problem.

I can supply details of a secure ftp site that only you and I
would have access to if you are concerned about security. (I would only pass it
on internally in Autodesk to our developers).
