We're having a problem running site maps greater than 4 levels deep. The generator consistently hangs with no error message. I've checked php.ini and upped timeouts and memory allocation. Currently, we're at 600 seconds for script timeout and parsing timeout, and 64mb memory allocation.
When I run level 4, it completes in less than 2 minutes with no errors. When i kick off a level 5 crawl, it won't even complete level 4 - stops about halfway through level 4.
Level 4 sitemap has a little over 6100 pages.
We're getting kinda desperate to run a more complete map because we do have some things not indexing properly on Google and we also need to check links at the next levels down. All help will be gratefully accepted!
