Thank you for your hints. My OpenFTS had that bug indeed,
however, the indexing did not finish and the machine
continued to be heavily loaded.
I tried moving the entries from search_observer_queue,
but that did not help either. As a last resort, I truncated
the static_pages table and disabled the "Static
pages" package.
The machine load is back to zero now -- page loads,
especially for admin pages, are still very slow, though.
I guess I'll have to hunt for some tuning tricks now.
And I do hope that having the database on a RAID-5 file
system was not such a bad idea...
Cheers,
Helge
