Synchronizing W3TC configuration over multiple servers

    Hi,

    I am setting up WP + W3TC in a multiple servers environment behind a load balancer.

    My workflow:
    1. do a settings change in one server.
    2. sync wp-content/w3tc-config/master.php and master-admin.php from that server to all others.
    3. delete /wp-content/cache/config/master.php on all servers
    4. call w3tc_flush_all(); on all servers.

    this transfers the settings but:
    1. the other servers don’t cahce pages (memcached, they produce them for every request)
    2. the other servers don’t output and expiry header.

    This is fixed with a visit to the plugin admin:
    wp-admin/admin.php?page=w3tc_dashboard

    What am i doing wrong, how can i fix this? (excepts for visiting the admin page on each server)

    Thanks, Tom

    Things i’ve made sure / tried:
    1. verify wp-cron.php – this runs and does not fix the problem on it’s own
    2. clean the whole memcached service’s content – also doesn’t work.
