I was running the XML Sitemap generator from command line PHP (usr/bin/php-cli) earlier today and it ran up until getting an out of memory error. I have 2GB of memory allocated to PHP, so I don't think it should consume more resources than that. The site it's running on is [ External links are visible to forum administrators only ], which is heavily interlinked.

Now I can't get it to run from command line or from the interface at all. On the interface, I don't see an option to run on the Crawling tab. When I run using /usr/bin/php-cli, then it stops after a few seconds. When I run using /usr/bin/php, then it stops with an HTTP 500 Server Error after a few seconds. However I can't see the error in my PHP error log.

The error that I got was "Allowed memory size of x bytes exhausted (tried to allocate x bytes)"

I don't remember the specific amounts now. I think the first number was the 2 GB from my php.ini memory limit though.

Now it just fails silently when I run in the command line.
