Description:
------------
I have tried this eight ways to Sunday.  I have created working test cases on multiple servers with different combinations of settings to try and figure out why the failover does not work.

We have php5.3.8, pecl-memcache-3.0.6, memcached-1.4.7 with repcached.

Upon session_start() a key is successfully created in memcache.  Repcached does replicate it over to the other server and can be verified by telnet.

When we simulate a failure, the session handler does not fail over to the next available server listed in the save_path.

Current configuration:

session.save_handler = memcache
session.save_path = "tcp://ip1:11211, tcp://ip2:11211"
memcache.allow_failover="1"
memcache.hash_strategy="consistent"
We have tried to get it work with and without the below ini settings in different combinations:
memcache.session_redundancy=2
memcache.redundancy=1


Test script:
---------------
<?php
session_start();

if(!isset($_SESSION['id'])) {
    echo "VAR NOT SET!\n<br>";
    $_SESSION['id']=rand();
}else {
    echo $_SESSION['id']."\n<br>";
}
?>
