hmmm, I'm not aware of how mod_survey handles this internally, but this
really smells like a Perl variable 'filling' up. you can only store a
certain amount of text in a Perl string.

try the following:

------------------------------------------------------------------
#!/usr/bin/env perl

$a = 'some text here; the more, the faster you will reach the limit';

while (1) {
        $a .= $a;
        print length $a;
        print "\t";
}
------------------------------------------------------------------

and see where it stops incrementing. :-)
