Error downloading Product Variants using 7.7.251

[RichWendrock]

We are using dataport 7.7.251 and ablecommerce 7.06 with Api version 7.6.14430.0. I am running Dataport in Compatibility mode on Windows 7.

When I try to download the product variants as a CSV file, it runs for awhile and then displays the following error

Exception Message: Exception of type 'System.OutOfMemoryException' was thrown.
at CommerceBuilder.DataClient.Api.ACRequestHandler.ProcessRequest(StringrequestXml)
at
CommerceBuilder.DataClient.Api.AuthenticationHandler.System.web.IHttpHandler.ProcessRequest(HttpContest context)

Any idea what is causing this?

When I get that message, it just means there is too much data for the system memory. I haven't got it on a download yet, but I do get it occasionally on an Able 5 to 7 export/import.

Hi Judy,
This is not a large store. We have perhaps 1,100 products. Are you saying the dataport utility tries to store all variants in memory before writing them to the CSV file?

Thanks for your response by the way...

I'm not sure what all Able does with creating the variants file.
I just ran a variants export on a site with 3367 products, chunk size left at 50, no custom mapping and didn't get a memory problem on my local computer - but I've got 8GM of ram. Resulting file was 2,888 kb.
I am using dataport 7.6, though.

Thanks for the information. I have 12gb memory installed and I am using dataport defaults, i.e. did not change the chunk size. I have been reading the dataport documentation again to see if I missed anything. I will post here if I get by the error.
