Bitcoin Core Repeatedly Crashing

[dragblaze]

Bitcoin Client Software and Version Number: Bitcoin Core 0.15.1

Operating System: Windows 10

System Hardware Specs:
Core i7 2 GHz processor, 8 GB RAM, adequate storage

Description of Problem: Bitcoin core crashes saying it cannot read from the database. Upon reopening the wallet is corrupt. I can salvage the wallet and initiate reindexing, which continues for some time before Bitcoin Core crashes again. Each time I make some progress in downloading the blockchain. Have excluded the bitcoin directory from on-access antivirus scanning. Also reinstalled Bitcoin Core which seemed to improve the situation for a short time. Any suggestions on what is wrong and how to improve stability of Bitcoin Core?

Seems like your blockchain is corrupted.
MAKE A BACKUP OF YOUR WALLET.DAT FIRST!
After backing your wallet up, go to %APPDATA%\Bitcoin and remove everything except wallet.dat.
Start your client again.

You'll also need to sync the blockchain again.

[dragblaze]

Thank you for the warning to back up the wallet.dat file. In my case my private keys are in an offline wallet (I use Armory). It is the public watching wallet that is having the trouble. I have already deleted the Bitcoin data directory and attempted to resync the blockchain twice. I will try it again and see if I get different results.

Appreciate the suggestion! If it ultimately doesn't work then I may just reconstitute the wallet from my paper backup.

After deleting the Bitcoin directory and launching again the application crashed overnight with this error:

---------------------------
Bitcoin - Error
---------------------------
Error: A fatal internal error occurred, see debug.log for details
---------------------------
OK   
---------------------------


The log says "database corrupted"

Stop Bitcoin Core. Go to the Bitcoin Core data directory. Delete the folder named "chainstate". Start Bitcoin Core again. It should prompt you about reindexing the database (if it does not, it will look like it is resyncing), click "Yes" when it does. It will now look like it is resyncing the blockchain. It is actually reindexing the blockchain, the blockchain is not being redownloaded. This will rebuild Bitcoin Core's internal databases and will take several hours.
