[SR-Users] Kamailio presence shared DB_text

Hi list! We use Kamailio 4.2 for presence BLF with DB_TEXT. And i want to make cluster with a few Kamailio's presences, to load balance. Can you please tell me - is that possible to use same shared DB_TEXT database with 2 or more Kamailio servers ? modparam("presence", "subs_db_mode", 3) modparam ("presence","dburl","/tmp/share/dbtext") 1-st server will handle SUBSCRIBE's and this Subscribe's should be accessible also from 2-nd server. Then PUBLISH'es will be sent to both servers in round robin algorithm. Will Kamailio's work with one shared DB or - i'll got some errors ? Maybe i'm wrong somewhere ? Thanks in advance. Kind regards Ewgeny
