Luc -

Something's up with fixed difficulty - I have my 4 s9's set difficulty (_diff1500). Been running stable with much lower invalid rate and higher sharerate for the past 3 days. About an hour ago I noticed a problem with one of the s9's. The difficulty is now auto vardiff.  My settings have not changed. I've reset the miners.

Any changes you've made?
