HI,
It always throws an error message at me. I tried raising the PHP limit to 128 MB and 60 seconds
You haven't actually done so; your memory limit is ~34 MB. You may be unintentionally overriding it with an .htaccess file or an ini_set() in LocalSettings.php.
I had already so. Then the script wanted to consume more memory, thus leading to another memory limit exhausted message. Alternatively, it stopped after 30 seconds with timeout. I raised the timeout to 60 seconds, then it stopped at 60 seconds, if not due to memory exhausting. It seems there's a loop somewhere...
