If the logs you have are still the same as your previous logs above then I suspected that some chip temp is fluctuating above 85c. Since you have a large number of HW or hardware errors some chips are overheating and the hashboard will automatically disconnect if it happens then you will get ECMM[4] because it's disconnected automatically for protection and it will attempt to restart.
Another thing that I noticed from your previous logs is that the fan speed is not stable.
What I would like to suggest is to try to set the fan speed to at least 80% or 90% and let see if it will run stable for long. Just try even you have low room temp.
To set the fan speed you must have the FMS tool and then go to diagnostic and put this command below
[b][{"command":"ascset","parameter":"0,fan-spd,90"}] [/b]
Fan-spd,90 it's a fan speed with 90% you can replace it with 80% or 100% to try if it fixes the issue.
Another solution that I would like you to try is to use the aging you can find it on the FMS tool along with the Diagnose it can calibrate all ASIC chips.
I got FMS installed. You suggested using aging which I do not see in the tool (I have tried V2.3.3 and V2.1.0). Do you know where I can find a list of commands or manual to know how to make the commands for the diagnose console? Doesnt seem to be in their manual. Thank you.
