Hi Mina, Thank you very much for replying. My machines are running Oracle java 1.7.09. so that might be the issue. (My machines are running Oracle java 1.7.09 from the beginning.)
I cleaned up the specific empty CF again, and the "hinted handoff of 0 rows" showed up again, and the "scrub system HintsColumnFamily" trick worked this time. I'll try to reproduce the situation and check the phantom TCP connections.
