memcached disabled by default?

As far as I know from the command-line installation from the tarball (in 3.22), memcached is disabled by default. I did not touch any memcached-related setting upon installation, though I installed memcached. I see that Koha is trying to contact memcached (and SELinux denies the operation):

Will Koha fallback to something else and live with it, or is this situation something to worry about? Nemo bis 12:20, 12 February 2016 (EST)
