Updating 100 products in admin

When trying to edit 100 products in admin/productsI get the error below, anyone let me know what is ?

Fatal error: Out of memory (allocated 32505856) (tried to allocate 46 bytes) in /homepages/40/d317098982/htdocs/core/db/mysql.php on line 92



Contact your webhost. It would appear that your server is out of memory (specifically the system core)

I would normally suggest that you increase the memory limit available from the config.local.php file however it doesn’t seem to be able to exceed 32MB.
