Description

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:
