IPC Listener thread dead when OutOfMemoryError occured.
-------------------------------------------------------

                 Key: HADOOP-7916
                 URL: https://issues.apache.org/jira/browse/HADOOP-7916
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Uma Maheswara Rao G


In one of our environments IPC Listner thread dead when OutOfMemoryError occured.
I see, we already handling the OutOfMemoryError. Here on OutOfMemoryError just log, close
the connections then wait for 1 minute and loop again.
Ideally this thread should not die here. But I can see the below log in Hadoop out logs and
thread dies.

Exception in thread "IPC Server listener on 65113" java.lang.OutOfMemoryError: Java heap space

Also did not find the OutOfMemoryError handling log message in hadoop log files.
My suspect is that, after handling OutOfMemoryError,  it is throwing OutOfMemoryError  while
logging? so, that it just exited silently?
