With the block chain growth it would be exceptionally nice to have build in database placement options in the QT. maybe even allow for automatic mirroring, spanning, and automatic wallet/DB backup.

I use -datadir command to place the database on a NAS for security and storage reasons, it's just not that 'slick' of a solution.

The blockchain already has automatically mirroring and spanning; that is fundamentally what the bitcoin client does in the peer-to-peer network.

The wallet is quite small, and you absolutely should be backing that up on a regular basis.

Thanks for the update.

Minor remark: I use -datadir as an option to keep my coins in a non standard directory (as an extra security measure against wallet stealers) and when I install a new version it removes the flag in the shortcut. So I have to manually add it again after the update. Would be nice if it was kept by the update.

Yay! Honestly, I have no idea what that means, but it seems like security fixes, so good job!

Any idea on if the attack was used or it's impact at the time?

Yes, it was used. Some lower memory nodes crashed.

Does the fix limit any functionality?

What do you think this means?

"Truncate over-size messages to prevent a memory exhaustion attack."

Quick question.

I was running bitcoind on a EC2 micro instance, and it kept crashing. I assumed it was due to low memory. I've since upgraded to a small instance.

Is it possible the crashes were due to these attacks and it can actually run fine on a micro instance?

Can anyone possibly back this up? Or does micro instances simply have too little RAM to feasibly run it? Otherwise going to try and run bitcoind on a micro instance again to see what happens.

Thanks for all the dev work!
