I upgraded two days ago and now cannot run the generator without running into an annoying memory error.  This did not happen on the previous version.

My site has about 30000 URLs many of which change quite often. 

Below is the error and my config.  Also, php.ini has memory set to 768M but I don't think that's the issue as it complains of only have 256M.  Perhaps it is being limited elsewhere?

PHP Fatal error:  Allowed memory size of 268435456 bytes exhausted (tried to allocate 50752026 bytes) in /home/www/xxxxxx/generator/pages/class.utils.inc.php on line 102
