After an update from 3.0.8 to 3.0.9 we are getting the following exception on every node for the query:

SELECT * FROM keyspace.table WHERE partition = 0 AND expiration_time < 1480519469368;

on the following table:

CREATE TABLE keyspace.table (
    partition int,
    expiration_time timestamp,
    phone text,
    PRIMARY KEY (partition, expiration_time, phone)
) WITH CLUSTERING ORDER BY (expiration_time ASC, phone ASC)
