VUGen - Error on large file upload -- memory violation : Exception ACCESS_VIOLATION received.

Hi,

I am working with VUGen 12.20. In my Web - HTTP/HTML script, I am trying to upload a large file, around 1.2 GB using  web_submit_data method.

When I try running the test, I get the following error:

Action.c(55): Error: C interpreter run time error: Action.c (55): Error -- memory violation : Exception ACCESS_VIOLATION received.

I do not fae this issue with the same script when I upload a 100MB file. Is there a need to change any runtime settings for large file uploads? Is there a limit to the size of a file that can be uploaded in VUGen or HP Performance Center 12.20?

Appreciate the help.
