Here gem and rails versions:
Gems:
delayed_job (4.1.5)
dalli (2.7.8)
memcached -h | head -1
memcached 1.4.25
Rails
Rails 5.1.5
I run the delayed worker via this file ./bin/delayed_job run
which looks like this:
require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'environment'))
require 'delayed/command'
Delayed::Command.new(ARGV).daemonize
When I run the command I get error: error log
The cache store configuration is the following:
config.cache_store = :dalli_store, 'localhost:11211'
I connected to memcache server
abv@abv:~/git/csrhub-frontend$ telnet localhost 11211
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

ti seems to work.
Then I tried to get data from the Rails console:
irb(main):004:0> Rails.cache.dalli.set('spree/app_configuration/admin_path', '/some/path')
=> 216172782113783808
irb(main):005:0> Rails.cache.dalli.fetch('spree/app_configuration/admin_path')
=> "/some/path"
irb(main):006:0> Rails.cache.dalli.flush
=> [true]
irb(main):007:0> Rails.cache.dalli.fetch('spree/app_configuration/admin_path')
=> nil
It seems to work. I can't find the problem. Any ideas are very much welcome! Thanks.
I printed the Dalli::Client between cache writes:
