When an installation employs memcached, it is important to follow this sequence when restarting servers: Common:Stop the Messaging Server

  1. Stop all application Servers
  2. Stop all memcached servers
  3. Start all memcached servers
  4. Start all application servers

Common:Start the Messaging Server

Considerations
  • Stopping application servers ensures that they aren't adding entries to the cache.
  • Stopping memcached makes sure that the cache is flushed.
  • Those two steps can occur in either order. It is the next two for which order is critical:
  • Restarting memcached first makes sure that a clean copy of the cache is available.
  • When the application servers come up, they use the clean cache.
