kafka/zk errors
we're getting hundreds of these errs with kafka 0.8 and topics become
unavailable after running for a few days, any ideas how to proceed?
kafka error 1 (had to recreate the topic as it became unavailable after a
few days)

Hello Alex,
Error 1,3 and 4 can be transient and expected if on broker
startup/bouncing/shutdown, error 2 indicates the request type is incorrect:
currently we only have up to type 10, which consumer client do you use to
consume data?
I am not sure about the ZK error, but it seems indicating the host/port is
not reachable.
