Hi all, Who are the SIP experts? I've noticed that Koha::Caches->flush_L1_caches() never gets run on the SIP Server, and this means that the SIP Server can get stuck with old cached values that can never be changed without a restart. I've opened https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23640 to look into this, but I don't know the SIP Server well enough to know off the top of my head which function best represents every request (or if we want to only do it per connection, but I don't know how often connection attempts are done with SIP). I can investigate this, but I figure it makes more sense to leverage other people's expertise first. (Note: If you couple this issue with https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13193, you can theoretically have a SIP server persistently running with invalid system preferences. Either we push #13193, or we update SIP Server to reconnect to Memcached after a fork, so that it doesn't inherit the socket connection from the master SIP process.)
