      Description

      Observed dfsclients timing out to some datanodes.
      Datanode's '.out' file had

      Exception in thread "org.apache.hadoop.dfs.DataNode$DataXceiveServer@82d37" java.lang.OutOfMemoryError: unable to create new native thread
        at java.lang.Thread.start0(Native Method)
        at java.lang.Thread.start(Thread.java:597)
        at org.apache.hadoop.dfs.DataNode$DataXceiveServer.run(DataNode.java:906)
        at java.lang.Thread.run(Thread.java:619)
      

      Datanode was still running but not much activity besides verification.
      Jstack showed no DataXceiveServer running.
