blockchain – bitcoind crashing as a result of inadequate reminiscence?

EDIT 3

Bumping my VPS to 1GB of bodily RAM stopped the crashing problem… UNTIL stated VPS ran out of disc area.

I added prune=10240 to my ~/.bitcoin/bitcoin.conf file such that the blockchain file would begin pruning transaction historical past upon reaching 10GB filesize (1024 MB * 10 = 10GB).

EDIT 2

This appears to be a reminiscence problem, not a VPN networking problem. I turned OpenVPN off and restarted bitcoind solely to see it silently crash once more.

I’ve now added a 1GB swapfile to develop the obtainable reminiscence area (threat is this may trigger efficiency points for the OS). Will replace as soon as once more if this solves the problem. If not, I’ll in all probability find yourself attempting to improve the VPS occasion to 1GB of bodily RAM from 512MB.

EDIT
Discovered some fascinating stuff within the log referring to tor…

I’ve put in the Bitcoin software program on Ubuntu 16.04. I will run bitcoind -daemon for a couple of minutes, however after some time the method crashes.

Curiously, I do not see any causes in ~/.bitcoin/debug.log explaining why this system might need terminated.

I believe a few issues:

1. Not sufficient disc area to retailer your entire blockchain. Nevertheless, I do not assume that is the case as working df - h reveals a mixed complete of solely ~41% disc consumption:


root@sf-vps:~# df -h
Filesystem Dimension Used Avail Use% Mounted on
udev 241M 0 241M 0% /dev
tmpfs 50M 3.1M 47M 7% /run
/dev/vda1 20G 6.3G 13G 34% /
tmpfs 247M 0 247M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 247M 0 247M 0% /sys/fs/cgroup
tmpfs 50M 0 50M 0% /run/person/0


2. Server just isn’t capable of obtain inbound messages as I am working a VPN. Is it doable that I am experiencing a networking problem, e.g. inbound site visitors to port 8333 (the default for bitcoind) just isn’t being allowed by means of my VPN? I can not bear in mind how one can change the VPN config to permit connections on particular ports, however that is the place I am trying subsequent…
