Orange Pi One, SETI@Home & RAM

[rj45jack]

I've posted this on the Orange Pi subreddit here: https://redd.it/5bqnghbut figured a more active community might be better.

 

I am using my Orange Pi Ones for SETI@Home, I also use Raspberry Pis for the same purpose. I've noticed since, around, Armbian 5.20 that SETI@Home(BOINC) won't stay running for any more than 6-12 hours. It's being sniped by Out of Memory. I've tried a few things, posted on the subreddit, but here is the short list:

• Logged Memory ---> Can dip below 100MB during usage but not often
• Enabled Swap/Increase Swappiness---> 0 to 10 (I don't care about SD Card life)
• Adjusted BOINC/SETI to use 75% memory

None of the above seems to have helped. The RPis seem to have no issue with this, with even less swap space and 0 swappiness. 

 

What can I do here, if anything?

We don't have report about any memory troubles of this kind. The simplest way would be to tryout new kernel (4.9+) when becomes avaliable. Currently is under development and is in working / non working state at the moment. Peek here and try OrangepiPC 4.9.0 if it boots / works for you. Note: serial console only.

 

Try also with recompiling seti@home from sources and check their manual once again ...

Thanks Igor. I've downloaded the beta image and will test it shortly, just waiting on a new SD Card.

I had a report with Linpack a while ago and now with OPi Zero (256 MB) even system processes got oom killed. Legacy H3 kernel sucks here IMO, switching to mainline helped with both issues.

Igor and Tkaiser;

 

Using the new kernel seems to have solved the issue. I've been running all my Orange Pis since the 16th with no OOM issues.

Hey rj45jack are you using the beta image from Orange Pi PC in Orange Pi One? Or you compile a new kernel?

Thanks
