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

[Alvaro Cornejo]

Hi,

Yes, the idea is to identify who is calling the opac-search.pl.

The opac-search.pl is not a service, therefore "someone" needs to run it.
Unless there is something that put it in a sort of endless loop or it hungs
up

Hope helps,

Alvaro
