there may have system crash due to sudden power outage in the past.

Can you update to a newer version of bitconid?
15.2 or something in the 17 branch?
The version you are running is vulnerable to CVE 2018-17144 https://nvd.nist.gov/vuln/detail/CVE-2018-17144

Either way it looks like something in the DB is corrupted.

Backup your wallet file (you are doing that anyway right???), remove the blockchain data and re-download.

/root/.bitcoin/blocks  ?
/root/.bitcoin/chainstate

You only need to delete /root/.bitcoin/blocks

You might want to delete chainstate (which contain all UTXO) and txindex (which contain all transaction index) folder as well since both of them will be recreated anyway and just in case if those two are corrupted as well.

sorry i forgot to update.

bitcoind is up and running, didnt crashed once since i cleaned up blocks directory and started bitcoind.

blocks are still being downloaded , current getinfo shows

blocks : 487116

so i guess, it will take a day or two to finish.

thanks
