preparelockunspent fails

Question

Hi There,

The command prepareluckunspent is currently failing constantly giving me the error below.

multichain-cli chainname preparelockunspent '{"EUR": 1}'

{"method":"preparelockunspent","params":[{"EUR":1}],"id":1,"chain_name":"chainname"}

error: {"code":-4,"message":"Error: The transaction was rejected! This might happen if some of the coins in your wallet were already spent, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here."}

Im not sure how to go about debugging this, where can I start?

Thanks for this. Did you share the wallet.dat file with any other nodes, or export then import the private keys? Also please let me know if you're using a native currency on your blockchain.

Hi there, no, I haven't shared the wallet.dat, nor have I done any export / imports.

We have issued a native currency on the blockchain, EUR.

Answer 1

This does sound like a bug in the alpha. Would you be willing to zip up the blockchain directory and send it to us by email? We'll then take a look here and try to work out what's going on. I'll send you a private message with the address. Thanks!

Answer 2

Thanks. We've looked into the file you sent and have found the problem, which was caused by a bug in alpha 9. It should be fixed in alpha 10 - please let us know if you need an advanced copy, or if you've managed to continue working in the meantime.

Comments

Good to hear, in the meanwhile I reconnected the node and no problems thus far, we will keep working on alpha 9 for now.

FYI alpha 10 has been released which fixed this problem. If you run multichaind for the first time with the parameter -reindex=1 it should clear up your wallet inconsistency.
