Full node on Raspberry 3: Out of memory

[JorisK]

Hi,

As the topic states:

1. I have a Raspberry 3+
2. I downloaded the binaries from bitcoincore.org
3. I have a simple bitcoin.conf which only states it should run as a daemon.
4. Everything fully updated.

And this happens:

2020-01-03T12:00:02Z Error: Out of memory. Terminating.

Anyone any clue?

There is an entire discussion on running on a RPi here: https://bitcointalk.org/index.php?topic=5196287.0

It's not simple but you can do it with some tinkering.

You need to configure your Bitcoin Core to use less resource. Try this answer https://bitcoin.stackexchange.com/a/50743

It looks like compile may run out of memory.

You could try 'free -m' option to check your free memory then if you need to you can add some swap space with the code below.

You many need to use sudo command for the swap space.

To add a 1gb swap file, in /swapfile:

Code:

sudo dd if=/dev/zero of=/swapfile bs=1024M count=1000
sudo mkswap /swapfile
sudo swapon /swapfile

After compiling turn OFF swap

Code:

Code:
sudo swapoff /swapfile
sudo rm /swapfile

add a 1gb swap file

if you can avoid it, don't create the swapfile on the SD card but instead on an external disk, preferably an SSD (swapping memory pages between the swapfile and RAM is a performance bottleneck). The constant writing to the SD card will kill the card far quicker than you would expect otherwise.

I'd be inclined to make the swapfile persistent, I usually do ...

Code:

sudo dd if=/dev/zero of=/swapfile bs=64M count=16

where count=4 = 256 MB , count=8 = 512 MB , count=16 = 1G , count=32 = 2G etc.

Code:

sudo chmod 600 /swapfile

Code:

sudo mkswap /swapfile
sudo swapon /swapfile

make swapfile persistent ...

Code:

sudo nano /etc/fstab

add at base of file ...

Code:

/swapfile   none    swap    sw    0   0

...

also for server ...

Code:

sudo nano /etc/sysctl.conf

add at base of file ...

Code:

vm.swappiness = 60
vm.vfs_cache_pressure = 50

desktop !
vm.swappiness = 10

check with ...

Code:

cat /proc/sys/vm/vfs_cache_pressure
cat /proc/sys/vm/swappiness

other useful commands ...

check for existing swapfile ...

Code:

sudo swapon -s

filesystem (diskspace) ...

Code:

df -h

...

running ...

Code:

top

in a new terminal window (or Screen) is always useful for monitoring %CPU and %MEM to gain a better indication of what is actually happening.

I've not run an RPi in a while, although as Carlton has said an SSD is the safer bet.

Awesome, I left out the mempool and lowered the signaturecache as well, and now memory usage flows around 500MB (I have 1GB).

Looks like I can move on, many thanks everyone!
