A method, system and computer program product for an asynchronous interconnection between nodes of a clustered database management system (DBMS). Node timestamps are provided when each of the nodes in the cluster are started. Two or more communication conduits are established between the nodes. Each communication conduit between a local node and a remote node has an associated session identifier. The session identifiers and the timestamp from the remote node are associated to each communication conduit and the associated local node in the cluster. A timestamp is received from the remote node at the local node when establishing communication to determine if the remote node corresponds to the remote node incarnation identified by the timestamp and if DBMS communication between nodes can be initiated.
