Title: What does "Flushing wallet.dat" mean? Post by: SgtSpike on June 22, 2011, 07:31:02 AM Currently, my bitcoind service is stuck doing it. I'd just like to know what it means if my wallet is being flushed. Sounds a bit frightening...

I am also wondering the same ? what's "Flushing wallet.dat" I can read in my debug.log Title: Re: What does "Flushing wallet.dat" mean? Post by: twobits on May 25, 2013, 06:37:53 PM Flushing in this context means to flush or empty out the memory buffers, and force the data to be written to disk. Now this does not actually always work with modern consumer grade drives, but that is what it is at least trying to do when it logs that message.
One interesting thing is it uses the line Code: dbenv.txn_checkpoint(0, 0, 0); to do this. While another section of code seem to have been written thinking this is a nop. Wonder what the actually behavior is. Title: Re: What does "Flushing wallet.dat" mean?

Generally yes, it's a good way to safeguard your coin stash for longer periods of time. They can be created entirely offline and then you send all your coins to the generated address without the wallet ever being online. Title: Re: What does "Flushing wallet.dat" mean?

So, as a follow-up, how do you "restore" a wallet with your keys? Title: Re: What does "Flushing wallet.dat" mean?
