We have tested it several times after moving to new server. We have deleted all, re-installed and re-configured it again and again, but it does not help.
After start of Sitemaps crawling it does not show progress as before and after about 300 to 400 pages it kills server. All domains and websites go down. You only can restart server via Plesk to make it work again. Afterwards you can go to index.php?op=crawl and then XML Sitemaps Generator shows that script is running and even shows the progress, but does not communicate. So any update of progress must be forced with 30 seconds updates or 60 seconds update:
Already in progress. Current process state is displayed:
Links depth: 2
Current page: XXXXXXXXXXX
Pages added to sitemap: 330
Pages scanned: 412 (26,934.0 KB)
Pages left: 36 (+ 1949 queued for the next depth level)
Time passed: 0:36:11
Time left: 0:03:09
Memory usage: 6,058.0 Kb
We also changed:
memory_limit from 128M to 512M
max_execution_time from 30 to 9000
but this does not change anything.
Server is a strong cloud server and has no issues with anything else.
Do you have any idea? Does XML Sitemaps Generator needs a new update to make it working again on most recent servers? Any help would be appreciated.
