             Summary: Add column family name when reporting OutOfMemory errors
                 Key: CASSANDRA-8259
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8259
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jacek Furmankiewicz
            Priority: Critical


When we get a Thrift error like this which causes a server crash:
```

```

we have no clue as to which column family was being queried. That makes it extremely difficult to troubleshoot which query in a complex code base caused this error.

We have multiple servers and they all throw a NoAvailableHostException in Astyanax at the same time, all in different parts of the code...so figuring out the root cause is an exercise in frustration that takes many hours.

At least listing the colum family in this message would save us COUNTLESS hours of troubleshooting.

We're on 2.0.8, JDK 1.7, RHEL 6
