Stack overflow errors

[Sudarshan Kadambi (BLOOMBERG/ 731 LEXIN)]

I recently saw some exceptions that I haven't seen in HBase before. The trace 
looks something like:

Exception in thread "RpcServer.handler=96,port=60020" 
java.lang.StackOverflowError
        at org.apache.hadoop.hbase.CellUtil$1.advance(CellUtil.java:160)

Is this a known issue? The RegionServer went into a hung state and all gets to 
that RS began to hang indefinitely. This is on HBase 0.96.
