If i enable "memcache-session.inc" in settings.php every time after I go to 'admin/build/modules' I get logged out.
To test it just hit refresh after you access that page. In any other page, everything is oki (the module works as expected).

I have less than 5 modules enabled and i don't think is there anyone that interferes with the memcache module.

Can anyone confirm this ?

I also experience this behaviour. It also happens after clearing the cache under Admin-Performance-Clear Cache. My configuration for memcache:

$conf = array(
'cache_inc' => './sites/all/modules/memcache/memcache.inc',

'session_inc' => './sites/all/modules/memcache/memcache-session.inc',

'memcache_servers' => array('localhost:11211' => 'default'),

'memcache_bins' => array('cache' => 'default',
'session' => 'default',
'users' => 'default')
);

Is this maybe happening because I use the same memcache server for users and sessions as for cache?

Well it seems like session and users need it's own server. When I changed to the config below, with two servers, the problem disappeared.

$conf = array(
'cache_inc' => './sites/all/modules/memcache/memcache.inc',

'session_inc' => './sites/all/modules/memcache/memcache-session.inc',

'memcache_servers' => array('localhost:11211' => 'default',
'localhost:11212' => 'cluster2'),

'memcache_bins' => array('cache' => 'default',
'session' => 'cluster2',
'users' => 'cluster2')
);

From the README, emphasis added:

Here is a sample config that uses memcache for sessions. Note you MUST have
a session and a users bin set up for memcached sessions to work.

I've changed this to read

Note you MUST have
a session and a users server set up for memcached sessions to work.

Otherwise, when you clear your cache, you blow away all the sessions.

I am having a similar issue, but get the white screen of death. Can anybody see the issue with my config in settings.php?

$conf = array(
'cache_inc' => './sites/all/modules/memcache/memcache.inc',
'session_inc' => './sites/all/modules/memcache/memcache-session.inc',
'memcache_servers' => array(
'127.0.0.1:11211' => 'default',
'127.0.0.1:11212' => 'filter',
'127.0.0.1:11213' => 'menu',
'127.0.0.1:11214' => 'page',
'127.0.0.1:11215' => 'session',
'127.0.0.1:11216' => 'users',
),
'memcache_bins' => array(
'cache' => 'default',
'cache_filter' => 'filter',
'cache_menu' => 'menu'
'cache_page' => 'default',
'session' => 'session',
'users' => 'users',
),

);

I just get the white screen of death. If I comment out these 3 lines it works fine:

'cache_page' => 'default',
'session' => 'session',
'users' => 'users',

The error in the nginx logs shows this:

*15794 FastCGI sent in stderr: "PHP Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ')' in /var/www/html/site_name.com/sites/default/settings.php on line 111" while reading response header from upstream, client: x.x.x.x, server: test-site-name.com, request: "GET /admin HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "qa.site_name.com"

The line 111 is this:

'cache_page' => 'default',

Please Help!
