                 Key: HADOOP-7121
                 URL: https://issues.apache.org/jira/browse/HADOOP-7121
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Critical
             Fix For: 0.22.0


We had a situation where for some reason the serialization of an RPC call's response was throwing OOME. When this happens, the exception is not caught, and the call never gets a response - the client just hangs. Additionally, the OOME propagated all the way to the top of the IPC handler and caused the handler. Plus, the Handler upon exit only logged to stdout and not to the log4j logs.
