If your Google Sitemap file is in “pending” status and you are worried that it will never come out of that status, I would not worry. Google recently posted an announcement that this is a known issue and they are working to resolve it.

The announcement was posted by Google’s JohnMu:

We have some worried webmasters, who I have notified not to worry. There are threads on this topic at WebmasterWorld and Google Webmaster Help, amongst others.

Like I said yesterday, Google Webmaster Tools is buggy, so don’t let the bugs, um… bug you out (sorry, I had to).

Forum discussion at WebmasterWorld and Google Webmaster Help.
