That's an unusual error and does look like it is the driver's problem.
Are there any errors prior to this one? Can you reproduce it with a
smaller test case or only with 200000 records? If you can put together
something self contained, I'd love to look at it. Another good diagnostic
tool is adding ?loglevel=2 to your connection URL to enable verbose
logging. With 200k records that's going to be a lot of info, but if
you're willing to share it, I'd be willing to take a look at that too.
