Description:
------------
Initially I have tested with the default php-5.3.3 RH php_mod version and php-pecl-memcached-1.0.0-1.el6.x86_64.
Then I tested php56 with more-php56-php-pecl-memcached-2.2.0-7.el6.x86_64.rpm, but got the same results.

I'm testing php_memcached with 2 memcache backends.
I have a script running that creates a session though php and than checks with memcached-tool if both memcached backends have this session.

I use repcached als memcached backend.

This works fine.
But when I stop one of the memcache backends I see that the server with memcached stopped still regularly is called to set the session and it is not retried on the online memcached service, meaning setting this session fails.


config used:

session.save_handler = memcached
session.save_path = "10.1.11.154:11211,10.1.11.156:11211"
memcached.sess_remove_failed=1



Test script:
---------------
if needed let me know.

Expected result:
----------------
The remaining memcached backend should have the session set.

Actual result:
--------------
The remaining memcached backend does not have the session set.
