There are two quick solutions to this problem and that is either configuring your Memcached to listen to localhost or completely stopping it.

Option 1: Configure Memcached Server listen to localhost

When running Zimbra mail server, memcached is a very important module because it helps proxy service achieve caching of upstream routes to mailstores on a per end-client basis - significantly reduces the route lookup time thus improving the total time required to process the request and boost performance.

Since now Memcached is necessary, let's configure our server memcached daemon to listen through localhost / IP Address instead of public.

Common error

Starting proxy...failed.
nginx start failed. reason: No available memcached servers could be contacted

NOTE: proxy server tends to stop working after configuration and restart of Memcached. Therefore run the following command


[zimbra@server1 ~]$   zmprov ms `zmhostname` +zimbraServiceEnabled memcached


[zimbra@server1 ~]$   zmproxyctl restart
