Tendermint based blockchain went down about once every 3 weeks, then once every 2 weeks, then once a week.
Sometimes it could restart itself, and sometimes it could not restart with such logs:
10:20AM INF Unlocking keyring
10:20AM INF starting ABCI with Tendermint
10:23AM INF Unlocking keyring
10:23AM INF starting ABCI with Tendermint

Only restarting the container or better restarting the server helps.
Now it’s also down, but even restarting the server doesn’t help anymore.
Server configuration:
DigitalOcean. 8 GB Memory / 4 AMD vCPUs / 160 GB Disk + 110 GB / AMS3 - Ubuntu 20.04 (LTS) x64
This node acts as the primary node to which the application backend sends requests. The other two nodes work correctly and do not crash.
- How to launch the first node that fell down?
- How can I fix the problem that it cannot restart itself when it crashes?
- How do I fix the cause of the blockchain crash?
- Is it possible to make one of the other nodes the master node?
