[Koha] High CPU usage, slow OPAC/Staff interface, with memcache

[Daniel Owens]

Thank you for responding, Alvaro.

I hadn't recently checked apache logs. I had been checking the apache 
error logs to see why apache was shutting down. But that seems to have 
been resolved with memcache.

But the CPU issue remains. I am guessing you mean the access log? I 
don't see much there. But maybe I am looking in the wrong place: sudo 
tail -f /var/log/apache2/access.log

If I find the right place, am I looking for a single IP that is 
accessing Koha repeatedly?
