this error

2019-06-19 12:01:36 *** System error: CDB : Error -30974, can't open database wallet.dat would indicate that the wallet dat file has become corrupt.

If you havent done so already make a backup of the wallet.dat file and keep it safe (while it may be broken, need to have something to come back to if needs be.

To resolve the issue, the best thing to do is to attempt to recover the private keys in the current wallet.dat file and import them into a new wallet.

There are a number of different ways to do this.

• use the dump/import wallet call in reddcoin-qt
• use an external tool to attempt to read the file.

for option 1, using the wallet

• shutdown Reddcoin and make a backup of wallet.dat, move that backup somewhere safe
• start Reddcoin
• disable staking (Help > Debug Window > Console > setgenerate false)
• unlock wallet (Help > Debug Window > Console > walletpassphrase )
• dump the wallet (Help > Debug Window > Console > dumpwallet "path_to_wallet_dump.dat")
• shutdown Reddcoin
• rename the wallet.dat > wallet.original (there should be no wallet.dat in the data directory)
• start Reddcoin (which will generate a new empty wallet.dat file)
• import the wallet (Help > Debug Window > Console > importwallet "path_to_wallet_dump.dat")

depending on the size, it could take a while to import as it will scan the blockchain to recover all known tx's for all known addresses if the original wallet.dat is not too damaged, this proceedure should recover all reachable private keys.

But please check wallet balance matches.

Else, will need to get into more details with you

Hmm Strange i have had no issues for years, I already have a backup of my wallet i will try using that and see if that fixes the issue.

Please let me know if everything is ok after restoring wallet. In the past, usually found antivirus or power failures to be the main culprit.

I will close the ticket, but feel free to reopen if the issue is not resolved

Fixed the issue thanks :)
