Checking Google analytics I discovered there are 100 bum links from a trashed page. I started that page, never published it, but instead trashed it. In building my sitemap the plugin glommed on to that page generating 100 error codes when Google crawled my site.
Hopefully I have corrected it for the next time Google comes around by permanently deleting that page. Why would this plugin include a trashed page when generating the sitemap?
Seems like a flaw to me.
