Cassandra-2.2.3 : Repeatedly facing "writing large partition error" even after multiple repairs

We have a 6 node each 2 datacenter Cassandra cluster production environment setup. We encounter large partition warning. We ran 2 successful repairs, still this is not getting resolved. How can I analyze and fix this?

BigTableWriter.java:184 - Writing large partition system_distributed/repair_history:rf_key_space:my_table (108140638 bytes)

Mode: NORMAL
Not sending any streams.

The system_distributed.repair_history table is not one that you really need to concern yourself with. Unfortunately, this can happen when a lot of repairs have been run. With 2.2, the only real solution is to TRUNCATE that table every now and then.
