Downloads break (too many records)

You can try increasing the memory and timeout limits on your PHP installation. You can define these settings in settings.php (in sites/all/default), in the .htaccess file, or in php.ini

max_execution_time = 60     ; Maximum execution time of each script, in seconds
max_input_time = 60            ; Maximum amount of time each script may spend parsing request data
memory_limit = 128M      ; Maximum amount of memory a script may consume (8MB)

Closing after lack of response.

Is there a way we can have this export in batches? I have over 36,000 submissions I need to download, and it makes sense that it shouldn't be trying to do this all in one go.

Two other possible solutions would be to have a textfield to specify which records to download say records 0-999, 1000-1999 or a drush command for exporting.

Subscribing, same issues. 120 sec and 200mb memory is not enough for over 4000 subscriptions

Subscribing, same issue.

This should be merged with #381068: Start and End Dates Needed for Submissions Export. I should also note the threshold for downloading in the 3.x version should be higher, after we added #423350: Improve efficiency of options in select.inc and other caching to the token replacement.
