AbleCommerce Shopping Cart Software

The exports of product variants doesn't seem to work. It goes very slowly and then just stops at record 3750. Anyone else have issues exporting variants for all products? Tried this multiple times over the past few days with no luck. Tried to attach a screenshot but it says .jpg are not allowed.
Gets stuck on this:

Total Products: 6603 Exported: 3750

AbleCommerce for ASP.NET
VERSION: 7.0.92.9168
Release Label: GoldR12

Although they don't show as a downloadable file in the admin, I did find some find files in the App_Data>DataExchange>Downloads folder but all the variant files max out at 102.38MB or 89886 line items in the CSV file. This is only about half of our catalog. Anyone aware of anything that would prevent this file from getting any larger? We need a export for all product variants.

It seems related to some memory issue on the server.

Is there any error log available?

And if there is a very large catalog, then please try exporting a limited number of products at a time.
