That sounds odd:
- do you have an idea of how many inserts per second / minute you think you are sending?
- Is is just one node thats flushing mem tables fast?
- Can you send the column family for the super busy CF (nodetool cfstats) 
- Can you send the storage-conf.xml
- Can you send the nodetool tpstats for the busy node.
