Description:
------------
Description:
------------
memcache extension allows for failover (memcache.allow_failover = 1)
and can be used as a session handler (session.save_handler = memcache)

Unfortunately when failover happens a notice is thrown at session_start().

session_start() [function.session-start]: php_network_getaddresses: getaddrinfo failed: Name or service not known

Failover still works but the page is completely corrupted.
The manual is misleading: Quote 
"memcache.allow_failover boolean

    Whether to transparently failover to other servers on errors."

session_start does not deal with this so we can stay "transparent".


Expected result:
----------------
silent failover

Actual result:
--------------
php notice:
php_network_getaddresses: getaddrinfo failed: Name or service not known

Change to correct package

Use display_errors = Off if you won't want to see any warnings/errors (you can always redirect them into a log file).

I can sure hide the errors but this still does not work as advertised..

I had the same problem after messing around with my /etc/hosts file. 
It was solved when I added back: 

127.0.0.1	localhost

which I had for some reasons removed. This made it difficult for memcache to use 
localhost properly - and therefor the error.
