https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=17833 --- Comment #1 from Olli-Antti Kivilahti <olli-antti.kivilahti@jns.fi> --- Created attachment 58554 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=58554&action=edit Bug 17833 - Memcached silently fails to _initilize_memcached() on the second time it is invoked When _initilize_memcached() is called the first time, it sets the 'ismemcached'-key and returns 1. When _initilize_memcached() is called the second time, the 'ismemcached'-key already exists and '' is returned (this default to False in Perl). Koha thinks that memcached is not in use and decides to use some other caching mechanism instead. Cache::Memcached::Fast returns undef on server error: https://metacpan.org/pod/Cache::Memcached::Fast#add Koha MUST listen to undefined, instead of False to define whether or not memcached is properly working. Also added simple helpful diagnostics to help identify and log when this memcached server connection problem arises. -- You are receiving this mail because: You are watching all bug changes.
