Just started mining at wafflepool with my Zeusminer Thunder x3. I see this repeated quite often in my log file, usually consecutively:

[2014-10-27 15:25:18] Unknown stratum msg: {"id":null,"result":[],"error":true}

[2014-10-27 15:25:18] JSON-RPC non method decode failed: (null)

Anyone know what this means? Thanks in advance for any help.
