(all sitemap files effected)

There is only 1 scedualed task. Verified there is no manual cron task in the background.

The schedualed task kicks off at 2am. I had deleted the older task in vb after updating, but it had ran for awhile (~week) doing task twice. Once at 2am and again at 3am.

Unsure why it is downloading 2x.

Thoughts?

Hello Alan,

usually Google checks whether sitemap exists (1st hit) right after receiving the ping and then puts your sitemap to processing queue, and downloads it for processing after some time (2nd hit).
