Hello,

I have installed everything necessary and setup a low difficulty sha256 altcoin (digibyte) to test solo mining. Unfortunately I get more rejects than acceppted shares. The server reports the following error
when inserting a share to redis:

01/26/2015 18:50:25 +01:00 [Error] [HybridStorage] [Digibyte] An exception occured while comitting share: ERR unknown command 'HINCRBYFLOAT'

The web frontend shows 0 speed though I did connect one S5 to the pool. I assume the problem has to do with redis, right?
