D7 Domain Access module doesn't work with Memcache module

Just a note abt modules not working well together.

Domain Access won't bootstrap when the Memcache modules is running. Log has errors like this:

Domain access failed to load during phase: 2. Please check your settings.php file and site configuration.

When i install domain without memcache, then switch memcache back on, i get blank screens or PDO errors like this:

PDOException: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') ORDER BY fit DESC LIMIT 0, 1' at line 1: SELECT * FROM {menu_router} WHERE path IN () ORDER BY fit DESC LIMIT 0, 1; Array ( ) in menu_get_item() (line 443 of /www/docs/d7test/includes/menu.inc).
