Server Restart Sequence
When an installation employs memcached, it is important to follow this sequence when restarting servers:
- Stop all application Servers
- Stop all memcached servers
- Start all memcached servers
- Start all application servers

- 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 before LongJump makes sure that a clean copy of the cache is available for the application server, when it comes up.
