Possible, but unlikely.  See
https://issues.apache.org/jira/browse/CASSANDRA-3537 for an example of
a  "memory leak" that wasn't.

You need to remove the hints data files to clear out the incomplete
hints from < 1.0.3; the bug that caused this was fixed in
https://issues.apache.org/jira/browse/CASSANDRA-3446 but if you had
already generated some they don't get magically removed.
