i had installed XML Sitemap Generator on my site
and works fine but since 3 weeks ago
it didn't generate or update the sitemap
so i tried to make it manually but it shows errors

# There was a problem while notifying Google. View result
# There was a problem while notifying Bing. View result
# Ask.com was successfully notified about changes.
# It took 5.22 seconds to notify Ask.com, maybe you want to disable this feature to reduce the building time.

i made the following steps

* disabled notify Ask.com
* reduce number of the posts
* increase memory usage

but no luck at all and has the same errors
also here is the Errors in debug function
