When exporting from submissions for a form with 3500+ submissions, I get a Server Error 500. The server logs show the below error:

[Wed Nov 14 10:15:44 2012] [error] [client] Premature end of script headers: php-handler
[Wed Nov 14 10:16:34 2012] [error] [client] Premature end of script headers: php-handler

hm yeah probably running out of some resource. We'll probably need to send multiple files (each with a maximum of X).


Is there any update on this issue? Do you need any further information about this?

I've implemented the ability to export a subset of submissions (i.e by date in c4c5473) so you can export year by year. The export logic has now been replaced to the default SilverStripe GridField logic so any performance enhancements will need to occur there.
