Description of problem: "A common problem occurs when multiple IP addresses within the same subnet are assigned to the same NIC. If we make a connection attempt to another address on the same subnet as one of those addresses, the connection attempt will not necessarily be routed from the address we want. In the case of the DLM, the other nodes will quickly drop the connection attempt, causing problems. This patch makes the DLM bind to the local address it acquired from the cluster manager when using TCP prior to making a connection, obviating the need for administrators to "fix" their systems or use clever routing tricks." -- lhh Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
