| | | | | | | | | | | | - Changed Rdma connection creation to allocate all necessary buffer memory immediately. This has the effect that no later buffer allocations happen which can fail so that once accepted connections won't fail because of lack of locked memory. - Fixed connection logic so we reject a new connection if we can't create the necessary handlers rather than kill the entire broker (this includes not enough locked memory) git-svn-id: https://svn.apache.org/repos/asf/incubator/qpid/trunk/qpid@697101 13f79535-47bb-0310-9956-ffa450edef68
