rpc command 'getnewaddress' returns used addresses?

[samspaces]

I was under the impression that the above mentioned rpc command in bitcoin core returns an unused bitcoin address.
After my last transaction I noticed when checking the confirmations, that the address had already received bitcoin.
My keypool has 10000 addresses, so lack of addresses can't be the issue. Is my understanding of the client wrong that 'getnewaddress' returns an unused address?

Thanks.

It should give you a new address every time. However, IIRC, there's sometimes it won't if the keypool has not been refilled recently. For the keypool to not be refilled recently, you would have had to have requested the number of addresses in your keypool since the last time your wallet was unlocked.

Could you post the debug.log?

That is exactly what I thought. But that is impossible, I have 10000 addresses in this wallet & rarely use it. What kind of debug were you referring to? From the debug.log file?

Yes, the debug.log file. It might have some info in there about why this happened. It also might not.

It just occured to me, I have 2 copies of the blockchain.
They run identical wallet.dat files, but the first won't know that the second has given out an address.
That must be it. My bad.
