Do you see any error in the cassandra log ? Check compactionstats ? Also check the OS level log messages to see if you are getting hardware level error messages.

We are pretty sure there is no issue with the network between the regions and all the nodes are up and running all the time. Is there any other reason for the hints accumulation other than the n/w? eg: wide rows or bigger objects? Any pointers here could be very helpful. b/w the hints gets processed after some point of time.
