I am running bcoin in docker container. This machine might have several reboots during sync if this information is important.
And this is the config:
# main, testnet
network: main
# Data directory
prefix: /data
workers: true
workers-size: 8
log-file: true
log-level: info
max-files: 8192
prune: false
checkpoints: true
index-address: true
index-tx: true
http-host: 0.0.0.0
api-key: <hidden>
Please, advise if this is normal? I also noticed that sync is going pretty slow, already for a week or so, but I am running it on 8-core VPS, which should be pretty powerful, and the chain is on SSD volume, taking already 723 GB, being just on 627509 block... Is it also normal?

Version bits
Sync time
I've found VPS notoriously slow for blockchain syncing, probably due to bottlenecked network access, especially on a shared server. 8-core CPU is nice and SSD is definitely required so it's probably this.
Config file
Also, where are you getting these settings for your config file? You are redundantly setting many default options and your http-host is very dangerous - anyone on the internet can reset your node or worse, steal your money!
network: main <<< DEFAULT
# Data directory
prefix: /data
workers: true <<< DEFAULT
workers-size: 8 <<< should be # of CPUs available by default
log-file: true <<< DEFAULT
log-level: info <<< DEFAULT
max-files: 8192 <<< Why are you setting this so high?
prune: false <<< DEFAULT
checkpoints: true <<< DEFAULT
index-address: true
index-tx: true
http-host: 0.0.0.0 <<< EXTREMELY DANGEROUS
api-key: <hidden>

version bits:
This warning is triggered because miners use overt Asicboost, which uses the block version number as a nonce. This means that blocks are produced with random version numbers, which triggers this warning.
The longer explanation is that the bits in the version field are used for signalling for rule changes (BIP9 / BIP135), in which the top three bits are reserved, and AsicBoost miners are using the last 16 bits.
suggestions:
- Add a meta warning that "this warning is probably nonsense, but could be serious".
- Drop the warning (This warning was removed from Bitcoin Core for 0.18.0 in bitcoin/bitcoin#15471.)
