Having the same issue as the following bug.
https://issues.apache.org/jira/browse/CASSANDRA-1346
I get the error when attempting to do super-column queries (one at a time, not
multi-threaded) as quickly as possible on a keystore with several hundred
thousand keys (each with ~1000 super columns, each with 0-1000+ columns).
Here is the stack:
