Hi Doru,

the image size starts at 400M, before doing anything on the model.

Now, as I start manipulating the model and sending navigation queries, trying to create an Arki report about the model, the image size apparently exceed 500M and the VM crashes!

For more information I enclosed the header of the crash.dmp file.

Cheers,

Hani

Hi,

What does large mean in your case? I routinely work with 500MB images on Windows 7 using the same VM.

Cheers,
Doru

521M is a hard limit for windows 32bit VM, sorry.

I think that it would be better for you to check 64bit version of vm..
or, as i suggested already, change your data model(s) and introduce
cache, or other memory conservation schemes.

thanks,
any idea about 64bit version of win vm? (url, name.....)
or an vm for Linux Mint 11 32 bit. Cogwin does not works on this version

Cog works on 32bit only for now.
