Dear friends That is problem #1
Here is problem #2 We have also noticed that opac-search.pl and mysqld is causing heavy loading.
Since a few days/week, we (BibLibre) face the same problem, on various Koha : on our hosting server (20+ libraries), some of our libraries that have their own server, small or large. After investigating a lot, we think it's because something happened with web crawler : we suddenly have *a lot* of queries coming from googlebot, bingbot and baidu (the chinese search engine). Plus some dark-net bots that try to exploit some security holes that are fixed (like reading /etc/password with a ../../../../../etc/password), but in case this Koha is not uptodate that could work. How did we fix that ? quick fix = drop packet at firewall level. We will have to investigate for a more long-term fix (not sure a robot.txt will be enough, but not sure it won't too) -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08
