I seldom use the LSA function. When trying I experienced the following:

Two surveys (modified copys):

Full responses 81
Incomplete responses 1055
Response summary Total responses 1136

Full responses 32
Incomplete responses 3142
Total responses 3174

Export Survey archive (.lsa) works fine when exporting the survey with 1137 responses.
When trying to export the survey with 3175 responses only a blank page is displayed.

It doesn't look or feel like a timeout from httpd or php. The blank is displayed in the same timerange as when the browser is offering the file dialog. No error messages.

Can anyone confirm that behavior?

Did you try to activate the debug mode ?

I really thibnk it's a memory or a time out issue.
Server log ?

An error happen ? Before make a new topic : remind the Debug mode .

I confirm what Denis said :
- when activating the debug mode, we get the following error : "Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 90 bytes) in /••••••••/framework/db/CDbDataReader.php on line 121"
- when increasing the max PHP memory, the problem disappears.
