Failed submit shares after some days running
Nodejs 8.9.3 CHS  2.5.0 
CHS is running OK for some days(like 2-5 days) then failed submit any shares. Only miner connected or miner disconnected or job submitted mesage in the PM2 console, no job arrived and shares accepted message.
Then upgrade to CHS 2.6.5, same situation happened after some days .
