I also have the same issue,in fact I get the 500 error on anything that I try to export whether it be one article or many.

Where in the server environment would we check for this limitation???

Also, does this also export the translated articles that have been translated using joomfish?

Please check that these are writable 777 on both sites:
administrator/components/com_export_content/img/...
administrator/components/com_export_content/zip/...
administrator/components/com_export_content/new_version/...

There is an interesting thread here on the jooma forums that may help.

There should also be more info in the server log files that might give a clue as to where the problem is.

You could have a look here to make sure you have the Minimum System Requirements:
http://help.joomla.org/content/view/1938/302/

Have you got iconv library enabled?
And have you got Jreviews installed as it has empty content items that will cause problems?

If none of the above helps google around for other solutions but basically it could be one of many different server settings causing the issue like "max packet size" for example.

If you workout what it was causing the issue please post back so others can benifit.

No not at this stage.
