I have 10 hashes per minute. How long will it take to find the block with the current difficulties?
Ubuntu 12.10, x86_64 bitcoind crashing after ~1 hour too. gives "error: couldn't connect to server"
right now difficulty changes a lot between block as much as a ten time factor sometimes that makes it difficult to give you a serious answer !
The error you get is just the daemon crashing, just restart it and you're fine, there's a more annoying crash that requires you to delete the .memorycoin folder (be careful if you have mined coins !)...
