[Koha-devel] Sessions terminated at random under Plack

[Tomas Cohen Arazi]

Magnus, there's been a lot of movement on the caching layer, and some of
that work has been backported to the stable releases. Also, the
RestrictSessionByIP setting was getting in the middle (
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=17050).

There's also a problem with memcached initialization in C4::Context that
makes sessionStorage=memcache fail to persist sessions.

My suggestion would be to set sessionStorage to 'mysql' and disable the
RestricSessionByIP syspref.

Regards
