I don't know it's a bug or not!my miner work find on cn-saber with 8K,but after a disconnected from pool and reconnected again,the hashrade drop to about 7300 and won't restore to 8K,i have to restart the miner to get 8K again... here is the log

You can see a Connection interrupted and reconnect at 05:04:11, then the hashrade drop to about 7.3K!This happend on all of my miners so i think i have to report this!
