Fatal error: Memory Size (from one day to another)

Hi Opencarters,

I'm running on OC 2.0.1.1 and I have an issue with JNeuhoff's Export/Import tool.

I'm using this tool successfully and without a problem a couple of month already and from one day to another I got the following error when trying to export my products:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 524288 bytes) in /home/buylandc/public_html/oc/system/PHPExcel/Classes/PHPExcel/Worksheet.php on line 1323

I did not change anything nor have the numbers of products increased heavily lately. 400 products shouldn't be too much.

Is there anything you can think of why this error keeps occuring all of a sudden?
Any help is much appreciated as I use the export/import tool daily to update my stock numbers.

Thanks.
Daniel

Never mind guys. I fixed it for the moment.

I allocated more memory on my php setting (i.e. from 128 to 256MB).
Since I'm running a shop with so few products the export tool shouldn't need so much memory, anyway.
