FD_SOCK timeout causing random test failures

    XMLWordPrintable

Details

    Description

      When a test doesn't require failure detection, we remove the FD protocol from the JGroups stack, but we keep FD_SOCK. Normally this isn't a problem, but in rare occasions it can fail to open the ping socked and the cluster doesn't form:

      22:51:45,978 DEBUG (testng-GlobalKeySetTaskTest:) [FD_SOCK] NodeA-60950: VIEW_CHANGE received: [NodeA-60950]

      We should increase FD_SOCK.sock_conn_timeout and remove FD_SOCK from the stack unless the test uses TransportFlags.withMerge().
