gsitemap-5.x-1.10.tar.gz has disappeared

I tried using XML sitemap on my site and it did not work. It gave some memory errors - I have 100,000+ nodes in the site.

So, I downloaded and installed gsitemap-5.x-1.10.tar.gz file. It was working OK on my site. I upgraded my hosting from shared to VPS now. But gsitemap is broken now. I tried to look for gsitemap-5.x-1.10.tar.gz module on Drupal.org and now that module version never existed on Drupal.org. I wonder how I downloaded it if it does not exist on Drupal.org site.

In gsitemap-5.x-1.10 was using chunk-size of 20,000 and it worked ok. Did not get any memory errors. Now, even if I reduce the chunk-size to 1000 it is not working and gives memory errors.

Any ideas? I dont care about chunk size - I just need sitemap to be fed to Google-bot.

I know XML sitemap is improved version of gsitemap and I will try XML Sitemap now to see if my problem is solved by that.

My config is:
- VPS with CentOS 4
- 512 MB ram
- MYSQL 5
- PHP 5
- Drupal core 5.1

Is this config sufficient for new XML Sitemap to handle 100,000+ nodes? Any experiences? I am trying to avoid having to upgrade Drupal core.

Thanks for help.
