ReserveKeyFromKeyPool(): read failed #2397

This happens when unlocking the wallet to create a new receive address. Happens every time, so unable to create new receive addresses currently.

(Bitcoin version v0.8.0-62-gb5ec091-beta (2013-03-21 10:08:32 +0700))

Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there.

Should be fixed with master / newer 0.8.x. If not please comment here or open a new issue.

I'm getting this same error ever since upgrading from 0.9x to 10+ now at 11.2. I get this error when trying to send bitcoins after entering my wallet password and when trying to create a new receive address. Both operations fail with this error and then bitcoin core crashes.

@FourthDr can you outline the exact steps that lead to your crash? Is it consistent?

Yes, it is consistent. I start bitcoin and wait over an hour for it to verify blocks, then scan. Once the client opens and I try to send bitcoin by clicking send, I get a password prompt, enter password click ok, then the client freezes and finally I get the error. With creating a new address, I get the error immediately after clicking create new address. :-( My last successful send was with 0.9 client.

I also tried installing bitcoin core 11.2 on a brand new install of Windows 7 that never had bitcoin installed on it. And It will never completely sync up. It gets to within 2 weeks, then starts crashing immediately upon starting the client. So I am at a loss as to what to do. I am dead in the water as far as bitcoin core is concerned. What was changed in the 10x & 11x client that has gone so hideously wrong??

So is there a dedicated support site for bitcoin core problems? Need this resolved asap! My coins are being held hostage!

As far as I know, no. Like for any open source project, support, if available at all, is provided by the community (or service contracts).

Anyhow: Looks like a corrupted wallet. What you could try is to backup wallet.dat carefully, and then run bitcoind/qt with the command line argument -salvagewallet. This will try to repair it as far as automatically possible.

maybe the dat file problem ?
