XML Sitemap Generator has notified errors

[iman24]

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.
# The building process took about 25.52 seconds to complete and used 26.25 MB of memory.

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

Mine started doing this a while ago and I assumed it was some kind of routing error, although I could successful connect to google and bing at the time.

In the end I just switched to BWP Google XML Sitemaps and it works much better.

is BWP makes new update in xml sitemap every time i made new post
or should i rebuilt it manually ?

BWP works by pinging search engines when you post something new. When a spider crawls your site, the sitemap it is rebuilt, hence why I think it is much better than the standard google sitemaps plugin (less load).

It sounds like you are having dns and/or routing issues and the name lookup error is almost certainly dns related. I would try changing the nameservers your server is using (see resolv.conf) or if you don't have root access, raise a ticket with your host.
