If this is happening on just one node and you don't have hundreds of tables in the cluster, it indicates that Cassandra is unable to flush the memtables to disk.

You need to look into why that is happening by going through the logs for clues. Cheers!

It is happening across all nodes in the cluster , if we look at system.log file there are frequent flushes happening , there are frequent repair/compaction as well
