OOM: "Out of memory: Kill process" happens when using apt-get command

[ForrestHong]

Hello

I got following error every time on my NanoPi NEO when running apt-get command.

root@NanoPi-NEO:/home/pi# apt-get update
Hit:1 http://ports.ubuntu.com xenial InRelease
Hit:2 http://ports.ubuntu.com xenial-security InRelease Hit:3 http://ports.ubuntu.com xenial-updates InRelease Hit:4 http://ports.ubuntu.com xenial-backports InRelease [ 1083.337086] Out of memory: Kill process 2204 (apt-get) score 117 or sacrifice child [ 1083.345843] Killed process 2204 (apt-get) total-vm:42564kB, anon-rss:34092kB, file-rss:2160kB Killed

This issue doesn't happen on the mainline Kernel. I opened another SSH session to check the free memory periodically, and I can see it should have enough memory for "LowFree”.

Could help to check this ?

Thanks

please offer info above:

1. ram size, 256 or 512MB?
2. full rom name, like nanopi-neo_friendlycore-xenial_4.14.0_20180511.img.zip

[ForrestHong]

Hello The RAM size is 256, and the rom NAME is “nanopi-neo_friendlycore-xenial_3.4.39_20171102.img.zip”， which was download from the link in wiki

[igorpecovnik]

Check https://www.armbian.com/nanopi-neo/ Armbian Stretch/Xenial with 4.14.y or Armbian Bionic (testing) with 4.17.y

[ForrestHong]

Hello igorpecovnik kernel 4.14 is ok, I've tried "nanopi-neo_friendlycore-xenial_4.14.0_20180511.img.zip" last week and it work as expected,

But, we need to use 3.4.x kernel because in our project, some of external device drivers are not supported in 4.x kernel.

Can this issue be resovled in kernel 3.4.x ?

I pasted the dmesg output after I issue "apt-get install tcpdump", at the bottom of the dmesg, there is a line "Killed process 856 (apt-get) total-vm:40820kB, anon-rss:32708kB, file-rss:736kB", does it mean that the vm was run out of space?

But, we need to use 3.4.x kernel because in our project, some of external device drivers are not supported in 4.x kernel.

Then still it is better to use our 3.4.113 kernel since it has a ton of fixes: https://github.com/armbian/linux + https://github.com/armbian/build/tree/master/patch/kernel/sun8i-default and perhaps this problem is solved.

Check for images in archive: https://dl.armbian.com/nanopineo/archive/

Hello igorpecovnik

Does Armbian support NanpiNEO-CORE board, we will finally use this board and burn the image(boot/kernel/rootfs) to it's board nand flash. which was described in following link:

http://wiki.friendlyarm.com/wiki/index.php/Assembling_the_SD_card_image_yourself

Thanks Forrest

[ForrestHong]

I see this link https://docs.armbian.com/User-Guide_Getting-Started/#how-to-install-to-emmc-nand-sata-usb it should support install image to NAND flash, I will try it when I go the NanoPiNeo Core board,

Anyway, I tried the Armbian image "Armbian_5.35_Nanopineo_Ubuntu_xenial_default_3.4.113.7z", and I didn't see the OOM issue when running the apt-get command.

I will keeping on testing this image.

Thanks Forrest

may be swap enabled or some kernel update?

[ForrestHong]

Yes, enable the swap can resolve this issue, I enabled the "zram" in kernel, and add following lines in "/etc/rc.local"

echo $((64*1024*1024)) > /sys/block/zram0/disksize && mkswap /dev/zram0 && swapon -p 5 /dev/zram0 &&

after that, i didn't see the OOM issue anymore.
