First time posting here, and long time lurker of the forums. Be gentle with me
Also not sure if this is the right section, but here goes nothing.

I know this topic has been discussed to death, but I am running out of options and ideas here, so hear me out.
One of my Antminer S9s recently started to act funny where it would shut down at random intervals and restart, or it would remain on and shut down all the hashing boards in the machine. It would seemingly run fine for a while before all the hashing boards begin to shutdown chips slowly, eventually leading to the machine coming to a complete standstill.
I restarted the machine manually every time I saw this issue from the web portal, and that seemed to resolve the issue momentarily. I then thought that the firmware on the machine had somehow gotten corrupt or malformed, and loaded other Bitmain firmware. The same issue occurred on every install.
I've loaded the S9 650M Firmware -

https://support.bitmain.com/hc/en-us/articles/360007577214-T9-Control-Board-Program-RecoveryI have a log from the machine, which can be found here -
https://drive.google.com/file/d/1dhcs6c2JyOHZhmhWyRvPwLeK0l_hyG8X/view?usp=sharingOn occasion, the Kernel Log will say that there is a RunTime Error with all the Hashing Boards, but this happens randomly.
Right now, the machine has got VNISH 3.8.6 loaded, and the log above is before VNISH was installed. I am starting to think that the PSU might be the culprit, but I am open to any suggestions as to how to fix this issue.
Any help at all would greatly appreciated, including SSH scripting.
Thanks for viewing!
