Bug Description
kairosdb server used to be filled up by data files and failed to write any more to cassandra. when we restore the kairosdb service, collectd client on some nodes couldn't restore the connection to kairosdb.
service collectd restart didn't help either and a socket remained open to kairosdb 4242 port. had to manually kill the process and start collectd.
Hopefully this can be fixed by udp mode of writing data.

Switching to UDP should prevent this type of problem. We will also modify the tcp code to be friendlier to the server.
