digibyte coin - groestlmyriad coin block-rejected!

[trustethorg]

I've setup digibyte myriad groestl algorithm for POOL.
also, changed to support myr-groestl hashing.

changed things:
multi-hashing support myr-groestl for digibyte.
getinfo api -> getblockchaininfo() , getnetworkinfo() , ...
for interfacing with digibyte latest daemon.
adds algoProperties.js to support myr-groestl
procedure to produce.
There's several days of mining. finally I found 3 blocks.
but, NOMP said
"(Thread 4) We thought a block was found but it was rejected by the daemon, share data: {"job":"a8d","ip":"18x.x.x.64","port":3270,"worker":"D8xq5XPZKAYMQ-----------------------,"height":6260408,"blockReward":79656798873,"difficulty":32,"shareDiff":"362533.21566225","blockDiff":314672.733261021,"blockDiffActual":314672.733261021,"blockHash":"0000000000002e46eb5923a74fe9150834595ead2c891364b2b0e673f02ba2f6"}

"

I don't know , why this happen, and digibyte daemon logs says nothing.

ambiguity points
I also need to change node-stratum on jobManager.js

for groestlmyriad ?
following is original code of node-stratum

    var coinbaseHasher = (function(){
        switch(options.coin.algorithm){
            case 'keccak':
            case 'blake':
            case 'fugue':
            case 'groestl':
                if (options.coin.normalHashing === true)
                    return util.sha256d;
                else
                    return util.sha256;
            default:
                return util.sha256d;
        }
    })();
