Raspberry PI 3 Out of memory

AlgoSDK
1

Hi everyone,
I’m trying to run my Raspberry PI 3 on MainNet.
goal process gone well during these days. I downloaded approximately 19 millions block, but now algod process crashing unexpectedly after a few seconds that it’s started.
I noticed that RAM grew until 90% and after the process crash.
In Algo folder my algod-err.log file is empty.

In /var/log/syslog I see this error:
Mar 26 07:08:45 raspberrypi kernel: [ 1652.281689] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0,global_oom,task_memcg=/,task=algod,pid=1370,uid=1000
Mar 26 07:08:45 raspberrypi kernel: [ 1652.281826] Out of memory: Killed process 1370 (algod) total-vm:1254052kB, anon-rss:854328kB, file-rss:0kB, shmem-rss:0kB, UID:1000 pgtables:1026kB oom_score_adj:0

Have you any advice?
I can change something in Algo configuration or apply some workaround?

Thanks a lot for your support.

Best regards,
Luca.

This is clearly lack of RAM: Out of memory: Killed process 1370 (algod)

How much RAM do you have?
You need at least 4GB.

That being said, I don’t think you will be able to use Raspberry Pi 3 smoothly.
SD cards are too slow. You need an external SSD on USB 3, but the Raspberry Pi 3 only supports USB 2 which is way too slow.

Hi Fabrice,
thanks a lot for your reply.
I mounted sd card of my Raspberry PI to my pc (Ubuntu 21.10, Intel i5, 8GB RAM) and restarted the node.
Node restarted without any problem.

Thanks a lot for your support.

Best regards,
Luca.
