Problems Exporting Entries

I am having problems exporting entries of this form:

https://loanapp.firstamerican.org/

I can specify a small range of a few days and sometimes successfully export a CSV file.

If I leave the date fields blank or specify a wider range, I get this error:

Firefox can't find the file at https://loanapp.firstamerican.org/wp-admin/admin.php?page=gf_export OR I get a blank CSV file.

I've had my webhost increase PHP memory to 32mb.

Here's what they said:

"I have checked your server PHP logs sent to /var/log/messages, and I do see some evidence that would point to a PHP memory limit issue, though it is not definitive. First, /var/log/messages will store logged information related to a PHP monitoring module - Suhosin. This module shows warnings that WordPress is attempting to allocate 32 MB of memory and is getting rejected as this is over the value defined in your /etc/php.ini:

[root@firstamerican vhosts]# tail -1 /var/log/messages
Nov 10 14:46:50 firstamerican suhosin[31791]: ALERT-SIMULATION - script tried to increase memory_limit to 33554432 bytes which is above
the allowed value (attacker '127.0.0.1', file '/var/www/vhosts/loanapp.firstamerican.org/wordpress/wp-includes/default-constants.php',
line 43)

Additionally, I checked the Apache error log to see if this script was generating any out of memory errors related to this, but I could not find any. Finally, I have checked your Database size for the 'firstamerican' database, and it is not large enough to cause any MySQL related memory errors.

To mitigate these issues with your form, I have increased the memory_limit in /etc/php.ini from 16M to 32M. This has halted the Suhosin alerts, I expect that this will resolve your issues; however, since this does not appear to be generating direct PHP errors I cannot be certain. If you continue to see any issues, please let me know exactly how I may replicate them. I would like to make sure that your Wordpress installation is operating to your satisfaction."

After that, the problem was still happening, so they have also increased the following values in php.ini:

upload_max_filesize
post_max_size
max_execution_time
max_input_time
memory_limit

The issue is still happening and I'm not sure what to try next.

Yes, after they increased the RAM, we still have an error. Rackspace said "does not appear to be generating direct PHP errors" after the memory increase but I still can't export the entries.

There are 280 entries, about 305 fields. No large quantities of text, no uploads.

I was experiencing the same issue trying to export my form with ~235 fields. The fields are all short text and numeric data. PHP was set to 64M of memory and no errors are being logged by apache in the error_log. Increasing the PHP memory limit to 96M fixes the problem.

On another note, submitting the form is also taking quite a long time, users were double submitting before I added some jquery to disable the button after submit.

Great. Thanks guys. Rackpace increased the memory to 128MB and they seemed to do the trick. I can export all entries for now.
