Thanks for the info.

My pi is 1200MHz @ +55C - so in the ball park.

I can't see how to post photos of the heatsink and fan combo on the pi, but it is the same as I use on many pi2/3 setups.

As a side note, I have about 15 pi machines running different things. I have no problems with pi1, pizero, pi2, pi3B+. But I do get issues with all pi3B. Weird!

Keith,

Thanks for the response - I reduced boinc/seti to 3 cores a week ago (or thereabouts).

I am not limiting the work units and see between 4-9 units being processed at any given time. Should I do something about that?

Is there a recommended config setting anywhere here I can use as a guide setting this up to run without errors or crashes?

How are my 'crunch' times now?

In 'top' I see all 4 cores running seti - is this wrong?

Everything was set to 'auto' when I set this up. If it needs to change then how do I do that?

Clock speeds should be default. I see nothing in config.txt that is changing clock speeds. Again, do I need to do something here and if so what please?

Thanks for the responses.

I moved from sd to ssd due to issues and sd was much worse in my experience.

I will look at the thread advised and see what I can learn there.

Hi,

Is there anyone here who can help with issues on a pi 3B running boinc seti?

Problems are.....

1. Sometimes I get 'error' or 'invalid' and don't know why.

2. Sometimes the pi just stops processing. No activity from the SSD and unable to ping or ssh into it. This might take days or weeks to happen, but then it requires a power cycle to get it going again.

I have a big heatsink and fan on the pi with a quality 5V6A psu connecting directly to the gpio pins. The extra current is for future upgrade to add a battery backup and this will then be able to charge and run at the same time.

I boot and run from a Kingston SSD connected via USB.

Thanks for any help or suggestions.

Thank you for the pointer - I will monitor it longer and see what I can find. I will post on the number crunching area if I can't sort it out any other way, but the last couple of weeks it seems to be more settled. Tech stuff huh? ;)

Hello!

I have been trying to get rid of processing errors with bonic running seti@home without much success.

I get several work units each week that show either 'error' or 'invalid'.

I have given the pi a quality power supply, eliminated the SD card and run only from SSD. I also added a big heatsink and temp controlled fan to keep the temperature lower and more constant.

So I wonder if others have found a reason or solution to this issue? Why does it happen? What can I do?

Thanks for the explaination, it's clearer to me now.

The info you have given I will try this weekend, seems easy when you know how (but that's always the way with software).... :)

Many Thanks!

Hi,

I can stop the boinccmd with boinccmd --quit to do updates and upgrades, but how to start it again afterwards?

Thanks, it's probably a simple solution, but I cannot see a start or run command anywhere.....

Hello! :)

I have a rpi3 running seti@home on all cores. But no matter how I shut the pi down, it always gives processing error message for current work units.

How can I cleanly stop the process (via SSH cli command) so that upon restart I no longer get these errors in processing?

Thanks...
