I'm experiencing periodical node restart, happening every minute or two. Happens on Ubuntu 20.04LTS, bitcoind version is v0.21.0. I'm running it as a systemd service using the following file:

Description=Bitcoin daemon
After=network.target

[Service]
ExecStart=/opt/bitcoin/bin/bitcoind -conf=/etc/bitcoin/bitcoin.conf -pid=/run/bitcoind/bitcoind.pid
# Creates /run/bitcoind owned by bitcoin
RuntimeDirectory=bitcoind
User=bitcoin
Type=forking
PIDFile=/run/bitcoind/bitcoind.pid
Restart=on-failure
PrivateTmp=true

[Install]
WantedBy=multi-user.target

This used to work just fine with an older version of bitcoind under ubuntu 18.

Now I'm seeing strange Ignoring unknown configuration messages in debug.log which I suppose should not be there, since it's a systemd config. Otherwise, the start seems okay.

1 Answer 1

Reset to default
3

After some testing, I figured out that Config file arg: [Install] daemon="1" was not working as expected and that the process does not want to fork. Therefore systemd tried to restart it forever.

I could fix this by moving daemon=1 to the first line in my bitcoin.conf file.
