On a different drillbit in the cluster, I found the below message for the same run
{code}
2015-02-20 00:24:08,435 [BitServer-6] WARN  o.a.d.exec.rpc.control.WorkEventBus - A fragment message arrived but there was no registered listener for that message: profile {

     endpoint {
       address: "qa-node191.qa.lab"
       user_port: 31010
       control_port: 31011
       data_port: 31012
     }
     message: "Failure while running fragment., Unable to allocate sv2 buffer after repeated attempts [ 66dba4ff-644c-4400-ab84-203256dc2600 on qa-node191.qa.lab:31010 ]\n"
   }
{code}

I attached the data file which only has 2 records. I manually copied over the 2 records 50000 times and ran these queries on top of them.

Let me know if you need anything else
