I upgraded to the latest version 6.1 from 6.0 (which in itself had been previously upgraded).
No problem with 6.0 and earlier releases.
However, 6.1 sits there with the "crawling" message for ever (i.e. for hours). I can see that debug and log files do not change at all. If I stop it (by clicking stop on the web page), I can restart it and it finishes about 5 minutes later. Although, I can only tell it has finished by looking a the log file because the crawl page still says crawling.
I am only putting about 700 pages into the sitemap and total time is only about 7 minutes.
What would cause it to hang?
I have upgraded gallery2 to gallery3 and also Joomla 1.5 to 2.5 since the last successful runs (which I recall also told me progress through the crawl). I get no crawl progress messages at all.
