Looks like this https://issues.apache.org/jira/browse/CASSANDRA-3975
Fixed in the latest 1.0.9. Either upgrade (which is always a good idea) or purge the hints from the server. Either using JMX or stopping the node and removing the HintedHandoff files from data/system. In either case you should then run a nodetool repair as hints for other CF's may have been dropped.
