wasn't PSU for me, I had a fan not working and that will get your machine to reboot. Took me about 5 hours to diagnose it lol!

I've owned hundreds of Antminers in the past year.  Presently I have 100+ of which I run approximately 25 at any given time.  ALL are on mobile racks and each rack mines a different algorithm/crypto.  I can mine ONLY two racks at a time due to electricity availability at my operation.  

Anyway.  I just spent the last 8 hours trying to diagnose a restart/reboot situation on an Antminer Z9 machine that has been running flawlessly up until yesterday.  Suspecting a bad hashboard, I unplugged ALL three of the hashboards and ran the machine with ONE at a time plugged in.  All three hashboards were fine and the machine would run fine with only ONE plugged in at a time.  BUT, as soon as any "two" were plugged in, "poof" restart and reboot every 60 seconds.  

It was through this posting that I decided to swap out the power supply and "VOILA"!!!  Yes INDEED, a faulty power supply that APPEARS to be working fine can be a "RESTART", "REBOOT" issue when this occurs.  The Antminer that I swapped out the power supply for is once again running LIKE A CHAMP!!

Yes, I do own "several" multi-meters and in the future, I will expedite this diagnostic "scenario" in the future.  If this ever occurs to me again, I will do DC VOLTAGE and DC AMPERE measurement before spending hours and hours and hours of "lost" time before swapping, plugging, flashing and pulling my hair out again!!  It's 8:00AM here, I started on my "restart/reboot" issue 10 hours ago and THANK GOD IT'S FIXED!!!  Drinking two pots of coffee and staying up ALL NIGHT to fix a machine is no fun!!

THANK YOU FOR THIS POST!! It's been "GOLD" in helping me find the solution to what could/should have been a very simple diagnosis for me.  The difficult problems I solve easily; the simple things take me a while..

Block halving is coming.
My Antminer s9 keeps reverting back to an old URL and worker address and its extremely frustrating because every few hrs, or even minutes sometimes, it will revert back to a previously loaded URL and worker address.  I have swapped out the PS and also tried uploading new firmware, but oddly, it gives me an error code everytime i try to upload the firmware.  its almost like the previous owner ran code into it so that it constantly reverts, so that when I am not paying attention, it starts paying him.  Please help....Below is the kernal log:


That's a different issue than the OP next time make a new thread about your issue.

Yours is common mostly hacked or sold miners from 3rd party that has this kind of issues.

The only thing that I could suggest about your issue is to try to flash it through an SD card if you don't know how to do it you can follow the guide from this link below.
- https://support.bitmain.com/hc/en-us/articles/360019493654-S9-series-S9-S9i-S9j-S9-Hydro-Control-Board-Program-Recovery

If it still doesn't work I suggest make another thread about this here in the same section. So that other experts are aware and to get some advice and better solution to your problem.

I also vote PSU as the first thing to check on. It soudns like its hitting its power limit randomly and going into protect for a moment which causes a reboot similar to unplugging and plugging the PSU back in

I have seen this problem on faulty PSU too, swap it and see how it goes.

Most commonly I have seen this as a PSU issue. Check on your PSU and power arrangement, and swap out PSU / cords etc. to see if that makes a difference.

We had a batch of 60 S9s sent to one of our facilities brand new from Bitmain. At least 10 of them began to do this after just one month. After a lot of trial and error, it was found to be faulty fans. Bitmain admitted to us that they had some fans with issues causing this. It may be worth a shot swapping out the fans.

On another note, sometimes firmware updates can be iffy. Sometimes when not fully successful, the chip temps or the fan RPMs will not be read correctly. This will cause the miner to continually reboot. Reverting back to an older firmware and running it for 15 minutes can rule this out.

This is not true...they will stall out and stop when they hit the overheating limit but do not auto restart. The status page will show the last status when it was mining, but otherwise it will just sit there until manually rebooted from heat issues.

maybe it's different from a firmware to another, but i am 100% sure that many of my S9s rebooted a few times when temps where high. i think your scenario happens when you check " stop running when temp is over 80c ", at that point the miner might stall, other wise if it passes i think "115c" it will restart.

check the temps, S9 auto reboot when temps are high

Have you tried to factory reset the miner? If not, you can follow this guide from here 3 ways to restore factory the s9 miner.

After that set the fan speed to high speed you can find the fan speed in secret menu if you don't know how to do this you can follow the guide from here https://bitcointalksearch.org/topic/solution-for-antminer-s9-fans-speed-up-down-every-20-seconds-2690140  

If the above solution doesn't work you can post the kernel logs here so that we can easily spot the problem. You can find the kernel logs from the miner dashboard> system >kernel logs. Then paste it here or in http://pastebin.com/
