OK, confirmed, Have had this firmware on my Baikal X10's ( 4 of them ) and still have same problem.
This is not new firmware for fix. we need to keep asking Baikal.
what is your setup? does each of you units have their own power supply? or are you sharing power supplies? what kin dof power supply are you using? did you make sure that each unit has its own worker? are you using the monitoring program? how hot are you running them? are you keeping it under 40 degrees c?
